Windows 10 (at least in my opinion) runs great on my two tablets (Surface Pro 3 and an OQO 2+). It's pretty clear that it's nearly ready for release. In theory it should be possible to install if you freed up a bit of space. My worry would be whether or not you'd lose the ability to dual boot into Android. ??? With it being so close to being officially launched, I reckon it would be best to hold off. With SD cards being so cheap now, ir might be worth purchasing a decent 64GB one. Windows 10 lets you install apps on the card, so you could keep some of that space free for updates.
