For these reasons, I don’t expect 2013 to be a good year for the conventional big-box PC. Instead I anticipate we’ll see more and more touchscreen all-in-ones that work sensibly with Windows 8. For businesses and budget-conscious consumers we already have compact systems such as the Intel NUC and the Apple Mac mini, and I wouldn’t be surprised to see more designs along those lines appearing in the new year.I don’t think Windows 8’s fully ambiguous "Is it a laptop? Is it a tablet?” approach will take off in the way Microsoft hopes. It simply doesn’t appear currently possible to come up with a hybrid design that’s compact and light enough to work really satisfactorily in tablet mode – and I’m not aware of any developments in the pipeline for 2013 that will change that. I expect the popular compromise will be conventional Ultrabooks with touchscreens.The exception might be Microsoft’s Surface Pro, which has generated enough interest and anticipation to be a minor hit, but price could well be a stumbling block: the 128GB version will reportedly cost $999 in the US, which probably means £799 or more over here. That feels like a lot to pay for such a device that looks and feels so much like a £400 tablet.

Surface In terms of what’s inside, again, the big news is Haswell, expected to arrive in the second quarter of 2013. In the absence of a breakthrough in battery cell technology (which doesn’t appear to be on the horizon), Intel’s new energy-efficient design is our best bet for improved battery life. Note though that Intel’s headline-grabbing claim of a "20x reduction in power consumption” applies only when the system is sitting idle. In practice I expect to see something closer to a 20% improvement.For those who don’t need the full power of an Ultrabook, Atom-based laptops are coming back too – and in 2013 they’ll be much more usable than the netbooks of yore, with decent screens and much snappier performance, partly thanks to the improved responsiveness of Windows 8 itself. I had the opportunity to play with a pre-production Atom-based system at IDF 2012 and was impressed.You don’t need psychic powers to see the Retina display filtering down into the MacBook Air rangeWhat of Apple? You don’t need psychic powers to see the Retina display filtering down into the MacBook Air range, but these panels still appear to be pretty expensive: right now the 13in 2.5GHz MacBook Pro with Retina display costs a whopping £450 more than the one without. That also covers an SSD and an extra 4GB of RAM, but it’s a strong suggestion that – alas – we won’t see a Retina screen on a sub-£1,000 MacBook Air in the next 12 months.

I also doubt we’ll see touchscreens on MacBooks in 2013. Apple has surprised us before with dramatic changes of direction, but so far with OS X devices it’s consistently preferred to build gestures and swipes into the touchpad rather than the screen. If I’m right about touchscreens becoming de rigueur in the Windows world, this will represent a major divergence: it will no longer possible to buy a MacBook and a copy of Parallels and truly get the best of both worlds.On the flip-side, I expect Retina-like screens will start to come to Windows 8 laptops. We’ve already seen several Android tablets appear with high-density panels, and the new Windows 8 app framework is designed to scale to arbitrarily high resolutions. Things on the desktop might not be so smooth, though: third-party application support for high-DPI screen modes is distinctly hit and miss. It might be worth sitting out the first generation of "Retina” Ultrabooks to allow for bugs to be ironed out.I don’t personally think Windows RT tablets will catch on. The platform is too dependent on an app store that’s too empty – and, so far as we can make out, growing very slowly. Maybe in time the Windows Store will mature into a credible rival to Android and iOS; but for the foreseeable future I think x86 hybrids, which aren’t wholly reliant on tablet apps for their usefulness, will be a lot more successful than "true” RT tablets.

What of the established players? As with Apple’s laptops, I think the iPad Mini must gain a Retina screen at some point – but again I won’t be surprised if it happens later rather than sooner, or comes in at a premium price. Bigger changes are hard to envisage: on paper it might seem to make sense to extend the screen to match the iPhone 5 and better accommodate widescreen video, but I’m not sure the result would be ergonomically sound. It’s been hinted that the next edition of OS X might include Siri and Apple Maps, so perhaps the focus in 2013 will be on yet-greater integration between mobile and desktop devices.On the Google side of things, Android 5 (codenamed Key Lime Pie) is expected to arrive in May, but as yet the feature list is shrouded in mystery – and it’s a depressingly safe bet that few older tablets will ever receive an upgrade. So if you want to get your hands on the latest and greatest version of Android, your best bet might be to wait, or to buy an official Nexus tablet.I scoffed when I first laid eyes on the Samsung Galaxy Note with its 5.5in screen, but I’m seeing more and more of them about – and regular smartphone screens have been getting bigger too (witness the iPhone 5, or the Galaxy S III with its 4.8in display). That’s probably because today’s big phones are powerful enough to serve as realistic alternatives to a tablet, and I expect the market for oversized handsets will grow in 2013. Screen densities will probably keep creeping up too, as in the tablet market.

Naturally the focus of these moves will be Android (as Apple chooses to offer only a very narrow and stable range of phones); but I suspect it won’t be all positive news for the platform in 2013, as the problem of malware in the Play Store grows bigger and more conspicuous. Although Google is working on the problem, the necessary technical and educational measures will take time, potentially making 2013 something of an annus horribilis for Android.For Apple users, we can assume an iPhone 5S will pop up in the autumn, presumably with a few whizzy new software features, but as with the iPad, there’s no great pressure on Apple to mess with the formula, especially so soon after a major update. Activity will probably be focused more be in the accessory market, as audio and video accessories are updated for the Lightning connector.The unknown quantity is Windows Phone 8. Microsoft’s new mobile OS hasn’t taken the high street by storm, but it’s received praise for features including its parental controls and the Data Sense tool that lets you monitor the data usage of apps. With HTC, Nokia and Samsung all invested in the platform, I wouldn’t write it off. It’s just a shame it doesn’t use the main Windows 8 Store: porting apps for the Windows Phone Store is easy enough, but the platform-agonistic appeal of iOS and Android is lost.For those still using Windows Phone 7, Nokia has started rolling out an upgrade to version 7.8, which brings much of the Windows Phone 8 UI to older phones, but since 7.8 won’t run Windows Phone 8 apps it doesn't have a long-term future.

It’s perhaps the most often-repeated advice in computing: "back up your data!” Yet many of us simply don’t do it, or don’t do it as often as we should. That’s understandable: duplicating and archiving your data feels like a chore – and, most of the time, a pointless one at that. But as the saying goes, there are only two types of computer user: those who’ve lost data due to a system crash, and those who will. In these days of iPads and smartphones you can also lose important data by literally losing it – or having it stolen. If you haven’t kept a backup, your photos, messages, contacts and more may be gone for good.Backing up your data will probably never be fun. But with the right tools and processes it can be largely automatic – which means there’s no excuse for not protecting your data. Sadly, there’s no single backup system that can protect all your devices in one go. But in this feature we’ll show you how to keep each of the devices in your home backed up with little or no effort, so that when a data disaster does strike you’ll be prepared.For most of us, the Windows PC remains the main repository for documents and media, so if you only keep one thing backed up, it ought to be this. Probably the most fuss-free approach is to invest in a continuous cloud backup service.

Backing up to the cloud has several advantages over using your own physical media. Because your backup destination is physically remote, there’s no clutter in your home – no stacks of external hard disks or boxes full of DVDs. Your data is safe from physical hazards, such as burglary or fire, and so long as the backup service uses strong encryption and data protection practices your personal information will be more secure too, as thieves will be unable to read it. Best of all, you never need to worry about running out of space. Many services provide unlimited space at quite reasonable prices.You can expect backing up a 100GB media folder to take more than three weeks of solid uploadingYou can expect backing up a 100GB media folder to take more than three weeks of solid uploadingThere are downsides to cloud backup, however. Clearly, you need a reliable internet connection: without one, you’re unprotected. The need for connectivity may also be a showstopper for laptop users who rarely connect to the internet, though we suspect those are a dying breed.Even if you do have a constant connection, your first backup may take a very long time to complete. Domestic broadband rarely offers more than 1Mbit/sec upstream, so you can expect backing up a 100GB media folder to take more than three weeks of solid uploading – tying up your connection and leaving you only partly protected in the meantime.

Lenovo was the first manufacturer to really nail the Windows 8 hybrid, and the Yoga 2 Pro sees it take the winning formula and refine it even further. With two new 11.6in and 13.3in models joining the ranks, Lenovo has retained the double-jointed hinge, streamlined the design and packed in Intel Haswell CPUs for good measure. The big news, though, is that the 13.3in model has also crammed in the small matter of 4.32 million extra pixels – it now has a high-DPI, 3,200 x 1,800 touchscreen.The beauty of the original Yoga was always its simplicity. Where other designs give away clues to their hybrid abilities with clearly unusual-looking screen bezels or telltale release catches, it’s impossible to recognise the Yoga’s split personality at a mere glance.The Yoga 2 Pro is no exception to this rule: from without, it’s just as you’d expect an Ultrabook to look; that is, gorgeous. There’s the same hardback-book-inspired design as the previous model, with dark, silvery metal lapping across the lid and base, and very slightly overhanging the edges. Gone is the predominantly square, somewhat frumpy profile of the original, however: the Yoga 2 now looks far more curved and streamlined, with its base tapering delicately up towards its front edge.
