Microsoft has just unveiled the free update of its Windows 8.1 operating system. So if the new features (covered in our Windows 8.1 tips and tricks feature) appeal you might want to buy yourself a new laptop. Windows 8.1 will be available on plenty of shiny new PCs from 18 October, here's the best ones out there now, or coming soon. And here's everything you need to know about Windows 8.1.

HP Envy17 Leap Motion Special Edition

Don't just get the latest Windows 8.1 OS, get the world's first laptop to feature Leap Motion controls built-in. This is ideal for the touchscreen interface of Windows 8.1, allowing you to control everything with nothing but your finger floating in the air. And with that mighty 17.3-inch 1080p display powered by Nvidia graphics you'll feel like you're in your very own Iron Man control room.

Beats graded audio and a backlit keyboard are also crammed into the aluminium chassis of the HP Envy17 Leap Motion SE. Get your hands on one this month with prices starting at $1050 (£653).

Samsung ATIV Book 9 Plus

As ever Samsung is out for Apple blood and this laptop puts the MacBook Air right in its sights. The 13.3-inch display is a stonking 3200 x 1800 pixels which equates to 276ppi. And despite being 13.6mm thin and 1.39kg it crams in a 12 hour battery, Intel Core i5 or i7 processor, up to 8GB of RAM and 256GB SSD. Plus it'll easily connect to your Android mobile and let you use it on screen using SideSync smarts. Pricing starts at $1,400 (£870).

Lenovo Yoga 2 Pro

This is where the lines between laptop and tablet blur a little. Since it's not detachable though we're classing it as a laptop. But there is a touchscreen and the keyboard can be folding right in behind for a 15.5mm thick, 1.39kg tablet of sorts. But primarily it's an Ultrabook with super efficient Intel Core Haswell innards and a 3200 x 1800, 13.3-inch touchscreen. Get the Yoga 2 Pro later this month for £1,100.

Dell XPS 15

The updated XPS 15 is, as you'd imagine, packing the latest Intel Haswell processors. It's also got an UltraSharp 15-inch display with a 3200 x 1800 resolution that looks great powered by Nvidia graphics. And the outside looks impressive too with a carbon fibre finish on the base, a well spaced keyboard and large trackpad all finished off with a brushed aluminium lid - weighing in at 2kg. There's also NFC for quick connections and plenty of ports to keep you going. Expect to see it on sale this month with a hefty price tag.

Sony Vaio Fit

Another laptop that verges on tablet territory is the Vaio Fit multi-flip PC. The backlit keyboard is attached but can be folded behind the 15.5-inch screen to be used as a 2kg tablet. As a laptop it boasts a 2880 x 1620 resolution screen, an impressive 8-megapixel Exmor RS for PC camera, digitiser stylus, Intel i7 processor and 16GB of RAM. Expect it to get a release date and price soon. It also comes in 13-inch and 14-inch versions.

Acer Aspire S7

For a slender, light and attractive laptop that also crams in power, this 1.3kg, 11.9mm thick beauty is the one for you. The S7, with its veneer-like finish and 13-inch 1080p screen, looks great as an ultrabook but also sports Intel Core i5 power, 4GM RAM and a 128GB SSD, plus a 12 hour battery life. Pick one up for £1,165.
