So how well does Win8 run on a tablet?
Very well on Intel based tablets and ARM based tablets coming soon!
.
Very well apparently.
There are plenty of reviews of the Samsung Windows 8 tablet(handed out by Microsoft at Build 2011 back in 2011), running a pre-beta windows 8 version. For the post part, the reviews were pretty good.
