The Asus VivoTab Note 8 is the best small form-factor Windows 8.1 tablet available. But even with its dockable Wacom stylus, the Microsoft OS isn't suited to smaller tablets.

Pros:
Wacom stylus, Windows 8.1 productivity services, bundled with Microsoft Office

Cons:
Dull design, average screen, small display means text and desktop applications can be fiddly to use
