If you hook the Surface Pro 4 up to an external monitor, you'll be happy to know that Windows 10 now supports per-display scaling, meaning you won't end up with giant windows and text a 24in Full HD monitor - one of the biggest gripes we had with every version of Windows before 10. To get anything done with great effect you will need to ensure Windows 10's display scaling options are set to 200% 100% is laughably difficult to read.

Text looks great, too, with no jagged edges in sight. Lines drawn with the Surface Pen are so smooth you can hardly tell they're on a screen at all. This takes pixel density from 216ppi up to a huge 267ppi - narrowly beating the 12.9in iPad Pro's 264ppi, if you're counting.

Screen resolution has also increased, up to 2,736 x 1,824 from 2,160x1,440 on the Surface Pro 3. Despite having the same footprint as last year's Surface Pro 3, thinner bezels mean the screen is 0.3in larger diagonally. Surface Pro 4 review: Displayīy itself, the Surface Pro 4 is a light, if slightly thick tablet with a 12.3in screen. I have the middle-of-the-road choice, so can't comment on the performance of the low-power Core m3 if Microsoft makes these available for review I'll see how big the performance drop is. Step up to a Core i7 and you'll pay either £1,499 or £1,799 if you want 16GB of RAM and 512GB of storage. Can't stomach that? Switch out the Core i5 for a fanless (and 20g lighter) Core m3 for a base price of £749. If you want to cheap out on a but keep the i5, half the RAM and half the storage, your tablet subtotal will be £849. Microsoft Surface Book review: Surface Book 2 is here, but what's new?
