Microsoft's Surface Book laptop has finally gone on sale in the UK, more than four months after being announced.
The Surface Book is a very high-specced laptop. Its 13.5-inch screen features PixelSense, which is the same technology found in the Microsoft Surface Pro 4. It has a 3,000 x 2,000-pixel resolution, a 3:2 aspect ratio and 10-point multi-touch.
Its pixel density of 267ppi is higher than a MacBook Pro.
Microsoft claims that the device's processor and dedicated GPU make the Surface Book twice as fast as the MacBook Pro. It's certainly not lacking on the grunt front. It boasts an optional Nvidia GeForce GPU and integrated Intel HD 520 graphics. Also onboard are 1GB of GDDR5 RAM and Intel Skylake i5 and i7 options.

As you can guess, these kinds of specs doesn't come cheap. Prices start at £1,299 and go up to £2,249 for the 512GB model. However, us Brits miss out on the 1TB model that Microsoft's US customers can buy.
You can pick one up from the Microsoft Store, Currys/PC World and John Lewis, among other retailers. (Though the cheapest model is currently listed as out of stock at John Lewis.) Trade in another device to Microsoft, and you could get up to £400 off.
Microsoft recently upgraded the device, announcing a model with 16GB of RAM.
