Apple did as many expected it would and announced an iPad Mini. We've pulled together the specification of Apple’s pint-sized iPad to compare it to Google's Nexus 7 tablet. Here's our Apple iPad mini vs Google Nexus 7 tablet comparison review.

Apple iPad Mini vs Google Nexus 7

Apple did as many expected it would and announced an iPad Mini. We've pulled together the specification of Apple’s pint-sized iPad to compare it to Google's Nexus 7 tablet. Here's our Apple iPad mini vs Google Nexus 7 tablet comparison review. Updated on 24/10/12. See also:Apple iPad mini review.

The iPad Mini has only just been revealed so this comparison is based on the specifications alone. To see what we really think of the iPad Mini check back for a full review soon. In the meantime enjoy this comparison and take a look at our iPad Mini preview.

The iPad Mini is a rival to the Nexus 7 because of its size. You could argue Apple created the iPad Mini deliberately to do so. Whether it did or not, here's how the iPad Mini stacks up against the Nexus 7.

See alsoGoogle Nexus 7 tablet vs Apple iPad comparison review.

Apple iPad Mini vs Google Nexus 7: Price

Google set a new benchmark price for budget tablets when it launched the Nexus 7. It starts at £159 for an 8GB model with a 16GB model costing £199. The price of the iPad Mini was one the most debated and unknown elements of the tablet.

We didn’t think Apple would go as low as Google, and it didn’t. The cheapest iPad Mini costs £269 for the 16GB model. This puts it at £70 more than the equivalent Nexus 7. However, a spanner may be thrown into the works since Google is expected to replace the 16GB model with a 32GB version for the same price.

Apple iPad Mini vs Google Nexus 7: Dimensions

With similar sized screens, the two tablets are of a similar size and weight. The Nexus 7 is smaller at 120 x 199mm compared to 135 x 200mm. The width is the main difference here.

However, as we predicted Apple made the iPad Mini thinner and lighter than the Nexus 7's 10.5mm and 340g. The iPad Mini measures in at 7.2mm and 308g for the Wi-Fi only model. The Wi-Fi and 4G model is an additional 4g heavier.

Apple iPad Mini vs Google Nexus 7: Screen

There was no surprise to discover that the iPad Mini has a 7.9in display. This is a little larger than the 7in screen found on the Nexus 7.

Google's Nexus 7 uses an 800 x 1280 resolution and as we predicted, the iPad Mini uses a 1024 x 768 resolution matching that of the original iPad and iPad 2 but on a smaller screen. This makes the aspect ratio 4:3 like all previous iPads compared to 16:10.

The iPad Mini doesn’t have as detailed a screen as the Nexus 7 - its pixel density is 163ppi compared to 216ppi.

Apple iPad Mini vs Google Nexus 7: Processor

Google's Nexus 7 is equipped with an nVidia Tegra 3, a quad-core chip along with a 12-core GPU. The iPad Mini is equipped with Apple's A5 dual-core processor which was used in the iPhone 4S and iPad 2. In the latter the chip is clocked at 1GHz.

Going by the processor specs, the Nexus 7 is more competent but the software the processor has to run is key to the performance.

Apple iPad Mini vs Google Nexus 7: Storage

As we mentioned earlier, Google has opted for only 16GB and 32GB models with the Nexus 7. The iPad Mini sticks to traditional Apple storage capacities of 16GB, 32GB and 64GB.

One thing the tablets have in common is a lack of a microSD for memory expansion.

Apple iPad Mini vs Google Nexus 7: Cameras

Google's Nexus 7 tablet has just a front facing camera rated at 1.2Mp, but the iPad Mini has more on offer with a 5Mp rear facing iSight camera and a 1.2Mp front facing FaceTime HD webcam.

Apple iPad Mini black slate

Apple iPad Mini vs Google Nexus 7: Connectivity

One big difference in connectivity is that the iPad Mini will use Apple's new Lightning connector brought into play with the iPhone 5. Google's Nexus 7 uses Micro-USB common to Android smartphones and tablets.

As you would expect the Nexus 7 and iPad Mini have Wi-Fi and Bluetooth on-board, although Apple’s tablet is dual-band and the firm is touting faster speeds via channel bonding. However, if it bothers you, the iPad Mini doesn’t have a near-field communications (NFC) chip like Google's tablet does.

There's no 3G model of the Nexus 7, although one is rumoured to be on its way. Apple offers a Wi-Fi and cellular model of the iPad Mini which, in the UK, supports 3G and 4G LTE frequencies.

Apple iPad Mini vs Google Nexus 7: Software

Software is an area where these tablets differ Touch Panel PC greatly. The iPad Mini will runs on Apple's own iOS 6 (with Siri) while the Nexus 7 tablet runs Google's latest version of Android, 4.1 Jelly Bean. Read our individual reviews of each for more details

Apple iPad Mini vs Google Nexus 7: Battery

The Nexus 7 has a 16Wh battery promising 10 hours of battery life when browsing the web over Wi-Fi. The situation with the iPad Mini is almost identical with Apple claiming 10 hours battery life surfing the web over Wi-Fi thanks to its 16.3Wh battery.

The Google Nexus 10 is a 10in Android tablet with a gorgeous HD display with superb front-facing stereo speakers, excellent performance and outstanding battery life. It also runs pure Google Android software and is guaranteed to receive future OS upgrades as soon as they're released. See Google Nexus 10 price in UK and specs.
The device does have very limited on-board storage, though, with no option to add extra space via an SD card. The Google Nexus 10 also has a plastic-based body that looks and feels less premium than some of the competition. See also: Group test: what's the best Android tablet?
But if you can stomach the storage - and don't mind the unassuming design - the Nexus 10 offers tremendous value at a relatively low cost. For anyone looking for a solid 10-in. tablet with a great all-around user experience, it's a tough act to beat.
The Nexus 10 is a bit different from Google's past efforts. The tablet, manufactured by Samsung, enters a realm that's already crowded with noteworthy contenders - and its price, while certainly low, is nowhere near as eye-catching as what we saw with the recent Nexus 7 and Nexus 4 devices.
The Nexus 10 will be sold directly by Google for £319 for a 16GB version or £389 for a 32GB model. So what's it like to use, and is it worth the cost? I've spent the past several days living with the tablet to find out.
Google Nexus 10: specifications and performance

Google's Nexus 10 is powered by a 1.7GHz Samsung Exynos 5250 dual-core processor along with 2GB of RAM. It's easy to get caught up in specs like the number of cores when talking about tablets (quad-core is quickly becoming par for the course these days), but it's important to remember that those numbers alone don't determine a device's performance.
The experience of using the Nexus 10, in fact, is more consistently smooth and snappy than what I've experienced with most other 10-in. Android tablets - including those with quad-core chips. Navigating through the home screens is fast and fluid, apps load instantly and multitasking feels effortless. Web browsing is a breeze, too, even with numerous tabs open in the Chrome browser. There's nothing to complain about in terms of performance here; the Nexus 10 absolutely delivers.
The Nexus 10 packs a 9000mAh battery that promises nine hours of nonstop video streaming, seven hours of continuous Web browsing and 500 hours of standby time. I found the tablet's stamina to be top-notch; even with moderate to heavy use, I was often able to go a solid few days between charges.
One area where the Nexus 10 falls short is in storage: The tablet's internal space is limited to either 16GB or 32GB. Once you factor in system files and all that fun stuff, even on the 32GB device, you're left with only about 27GB to 28GB of actual usable space -- and the device does not have an SD card slot for external storage. As with its Nexus 4, Google is clearly putting the focus on cloud storage and Web-based streaming, but that kind of configuration isn't going to work for everyone.
The Nexus 10 has two cameras: a front-facing 1.9-megapixel, 720p camera for vanity pics and video chat; and a rear-facing 5-megapixel, 1080p camera for stills and general recordings. When it comes to still pictures, the cameras are okay but not great; they'll get the job done, but you'll get far better quality from pretty much any current high-end smartphone camera. (Does anyone actually take photos on a tablet, anyway?)
Google's Nexus 10 supports near-field communication (NFC) for contact-free sharing and services, including Google Wallet, which comes preloaded on the device. Contrary to some reports, the tablet does not support the new Miracast wireless display-sharing protocol announced for the Nexus 4.
The Nexus 10 is currently available as a Wi-Fi-based device; at this point, Google has not announced any plans for a 3G- or 4G-capable version.
Google Nexus 10: Body and display

In terms of design, the Google Nexus 10 feels very much like a Samsung tablet: The device has a plastic-based construction that comes across as more utilitarian than premium. This isn't necessarily a bad thing, but it's a significant difference from the sleek and metal-centric approach used by products like the Asus Transformer Pad Infinity and Apple's iPad. (Of course, the iPad is more expensive, with a 16GB model costing £399. The Transformer Pad has a higher starting price, too, but it's actually in line with the Nexus 10's higher-end offering: £380 for a 32GB tablet.)
The Nexus 10's casing has a rubberized sort of feel that's pleasant to the touch; the tablet is easy to hold and never feels like it's slipping out of your hands. At 603g and a 8.9mm thickness, the device is relatively light and thin, too - more so even than Apple's latest offering, which comes in at 652g and 9.4mm.
The Nexus 10's best physical attribute, however, is its face. The tablet boasts a striking 2560-x-1600-pixel, 10.1-in. display with 300ppi, making it the highest resolution screen on any tablet today - the kind of resolution you'd typically see on a 30-in. computer monitor. The iPad, for comparison, has a resolution of 2048 x 1536 with 264ppi.
The Corning Gorilla Glass 2 screen is every bit as sharp as you'd expect: colours pop and details shine with a level of clarity that simply delights the eye. Watching HD videos - movies, in particular - is just an awesome experience on this device, particularly when you factor in its dual front-facing stereo speakers, which provide the best on-board audio of any tablet I've used.
The only negative is the Nexus 10's built-in autobrightness feature, which I found to be rather erratic: Regardless of where I used the tablet, the screen's brightness would randomly fluctuate every 30 seconds or so, even when I was holding the device perfectly still in stable lighting conditions. This seems to be a consistent issue with Samsung-made mobile products.
The Nexus 10's speakers are built into a plastic bezel that surrounds the Touch Panel PC display and extends seamlessly onto the device's sides and back. The left side of the unit houses a 3.5mm headphone jack along with a micro-USB port. That's right, folks: The Nexus 10, unlike most tablets, actually charges via a standard micro-USB connector instead of a proprietary alternative. (Hallelujah!).

The tablet has a power button and volume rocker directly next to each other on the far left of its top edge. That placement is somewhat unusual; the side of a device is a far more common spot for volume control. It's a minor detail, for sure, but even after a week of using the Nexus 10, I find it feels slightly unnatural to press left or right instead of up or down on the volume rocker to adjust the sound level.
On the right of the tablet, you have a dedicated micro-HDMI port -- no special adapter or connector required there, either. The device's bottom, meanwhile, has a magnetic charging port, presumably for future docking accessories.
The Nexus 10's back is a single piece of hard plastic, save for an inch-and-a-half-tall panel of removable material surrounding the camera at the top. The removable panel is another very Samsung-like touch; it's thin, flimsy, and feels like it'd be all too easy to snap in half. I was actually worried I was going to break it when I first peeled it off my device (thankfully, I did not).
Why would you even peel the panel off in the first place, you might be wondering? Unlike many Samsung-made phones, the panel doesn't give you access to the device's battery or other interiors. It does, however, serve as a placeholder for an optional cover accessory; Google sent me a bright red cover to try out.
Once attached, the cover flips around the top of the device to protect the screen. It also serves as an easy on-off switch: With the help of a hidden magnet, the cover automatically activates the Nexus 10's display when you lift it up and puts it to sleep when you place it back down. It's a nice touch that -- particularly with the way it integrates naturally into the tablet's form -- makes the product feel more complete.
(Google says the covers will be sold directly through its Google Play Store but has yet to release any info about their pricing or when they'll be available.)

Technology Spectator

If you're looking for a poor man's notebook you might be disappointed, but there's actually more to Microsoft's Surface than meets the eye.

Microsoft is a latecomer to the consumer tablet revival but it's gone back to the drawing board with Windows 8, delivering a range of gadgets which are built from the ground up with touchscreens in mind. First out of the blocks were the new Window 8 touchscreen notebooks such as the Acer Aspire S7, but Microsoft's $559 Surface tablet presents a more intriguing taste of things to come.

The Surface sports a bright 10.6-inch, 1366 x 768 display which does an admirable job of handling outdoor glare. Hefted for weight it feels identical to Apple's original 9.7-inch iPad at 680 grams, but thinner and with a larger footprint. The taller 16:9 display also feels awkward in portrait mode if you're familiar with Apple tablets. The Surface feels more natural in landscape mode and has a built-in kickstand for resting on its side.

You wouldn't call it ugly, but the Surface is no sleek and slender fashion statement like the iPad 4 or petite iPad Mini. That's forgivable because, as is often Microsoft's way, the Surface puts substance before style. Turn it over in your hands and you'll find front and rear cameras, along with a micro-HDMI video output, full-sized USB2.0 port and micro-SDXC card slot to complement the 32GB or 64GB of onboard storage. Such impressive connectivity options are a taste of the versatility to come as you delve into the Surface. You also enjoy access to 802.11b/g/n Wi-Fi and Bluetooth 4.0, but there's no sign of 3G/4G cellular models at this stage.

Under the bonnet the Surface sports an Nvidia ARM processor designed for mobile devices, rather than a traditional x86 chip from the likes of Intel or AMD. It's easy to get bogged down in the spec sheet but the choice of processor is critical. Shunning x86 architecture in favour of ARM means the Surface only runs a stripped-down version of Windows 8 known as Windows RT. For this reason you'll sometimes see the Surface referred to as the Surface RT, to distinguish it from the upcoming Intel-based Surface Pro which will run a full version of Windows 8 Professional.

An overgrown Windows phone?

At first glance it appears the Surface is merely an overgrown Windows Phone which can only run the new tablet-style Modern UI found on all Windows 8 devices (formerly known as Metro UI). But just as with a Windows 8 computer, it is possible to brush aside Modern UI on the Surface for the comfort of the traditional Windows desktop (albeit sans the Start menu).

The temptation is to rush straight to the desktop but, to be fair, you can do quite a lot in Modern UI once you learn your way around. For starters you've got access to touch-friendly versions of Internet Explorer, Mail, Skype, Calendar and Contacts. Add to these a range of consumer-friendly apps such as Music, Photos, Videos, Games, Maps, News and Weather. Everything is tied together with Microsoft's cloud services – Office 365, SkyDrive and Hotmail (now renamed "Outlook.com", just to confuse things).

Modern UI is slick and responsive thanks to the 1.3 GHz quad-core processor and 2 GB of RAM. Performance is helped by the fact that Windows 8 uses intelligent resource management to ensure it doesn't grind to a halt when you open too many applications at once. You can run two apps side-by-side, with one taking up the left or right quarter of the screen.

To expand your horizons the Windows Store offers a small but growing range of iOS-style touch-friendly apps – from Angry Birds Star Wars and TuneIn Radio to the more productive Evernote. The promise of running these app across all of your Windows 8 devices is one of the platform's strengths. Meanwhile, Remote Desktop and RemoteApp open up possibilities for professionals relying on Line of Business applications.

While they're useful for many day-to-day tasks, it's important to appreciate that these Modern UI offerings are stripped down single-window apps. This can be frustrating from a productivity perspective, but the Surface's hidden gem is that it actually runs the "Office RT" applications Word, Excel, PowerPoint and OneNote on the desktop rather than in Modern UI. Here you can open multiple documents at once and easily move between them, just like on your desktop PC, rather than struggle with a simplified touch-friendly interface.

Keep in mind this is the non-commercial Home and Student edition of Office, so businesses will need to consider their licensing options. Meanwhile, you'll also find versions of Microsoft's Skype and Lync in the Windows Store, designed to run in Modern UI.

Back on the desktop you've got access to many of Microsoft's pre-installed native applications such as Internet Explorer, Paint, Notepad and Powershell as well as utilities like the Control Panel and Task Manager. What's really impressive is that you can run a Modern UI app on the side of the screen while still dedicating three-quarters of the display to the desktop.

Starting to look like a 'real' computer

About now the Surface is starting to look like a "real" computer, with Modern UI as an optional extra, and it seems a shame that it doesn't feature a physical keyboard. But look more closely. On the bottom edge of the tablet you'll find a magnetic docking port for Microsoft's optional $119 Touch Cover or $150 Type Cover which feature built-in keyboards. The Type Cover offers very shallow keys while the thinner Touch Cover only has a pressure-sensitive keyboard etched into it.

The Touch Cover feels disconcerting at first but offers decent-sized keys along with a small but usable trackpad. It might satisfy occasional typists but wordsmiths would want to weigh it up against the Type Cover. Thankfully the Surface also supports external keyboards and mice via Bluetooth and USB. Even with a Cover attached the Surface is more awkward to balance on your lap than a well-balanced notebook. When it's sitting on a desk you'll lament the fact that the kickstart isn't adjustable so you can't alter the screen angle.

Once you throw in Office on the traditional desktop and a physical keyboard, the Surface looks less like a consumer toy and more like a portable productivity device. Office RT is likely to satisfy most users but it has its limitations. For example it's missing Visual Basic for Applications and support for macros, add-ins and other features that rely on ActiveX controls or third-party code. Excel power users could feel the pinch, along with road warriors trying to incorporate legacy media formats into PowerPoint.

There's also no mail client for the desktop such as Outlook or Outlook Express, which comes as a shock to the system when you've just become comfortable with the desktop. You could use Internet Explorer to access webmail on the desktop. Alternatively you could flick back to Modern UI and use the Mail app which supports Exchange, IMAP and several flavours of webmail.

Remember you're stuck with Windows RT so you can't simply install your own desktop mail client of choice as you would on a Windows 8 PC. If you need something like Outlook, Photoshop, Pagemaker or InDesign you're out of luck. It's not an artificial restriction which can be bypassed by sneaky side-loading, it's a physical limitation of the hardware. Leap into Windows Touch Panel PC RT without appreciating this and you're in for a world of disappointment.

A mixed bag for enterprises

Windows RT also offers a mixed bag for enterprises. It supports Exchange ActiveSync for Mobile Device Management features but not Active Directory for connecting to in-house resources. This alone could be a deal-breaker for some businesses and you'll certainly need to do your research before bringing Windows RT into the fold. For now IT departments should perhaps best view the Surface as a glorified iPad.

If these kinds of limitations will frustrate you then perhaps you should hold out for the Surface Pro, which we should see in January, or else a third-party tablet running a full version of Windows 8. Yet if these limitations frustrate you then you might be missing the point of the Surface.

So what is the point of the Surface? Good question, but it's one you'll need to answer for yourself. Generous observers would describe the Surface as a touch-friendly iPad rival, with a less-diverse app store but the benefit of true Office compatibility. The icing on the cake is interoperability between Modern UI devices and tight integration with the Microsoft, Office and Xbox 360 ecosystems.

The more pragmatic might describe Microsoft's Surface as a dumbed-down notebook replacement, given a touch-friendly coat of paint in a futile attempt to compete with Apple's all-conquering iGadgets. At $559, plus a keyboard cover, you have to ask yourself why you wouldn't simply pay more for a Windows 8 ultrabook or pay less for an Apple or Android wundertablet.

You might point to weight or price alone as factors in the Surface's favour, but it doesn't matter how much a gadget weighs or how much it costs if it's not the right tool for the job. To fall in love with the Surface you'll need to find a task which it performs better than any of the alternatives, so much better that it outweighs the many limitations of Windows RT. Otherwise you might be better holding out for the Surface Pro or else throwing your lot in with Apple or Android.
