Surface Pro will be 1920 x 1080. Microsoft claims that the 1366 x 768 screen will look better than their competitors because of sub-pixel rendering in ClearType and the way they made the screen. We will have to wait for some public side by side comparisons to see if that is actually true.
Upgraded both my workstation/gaming rig and laptop to Windows 8 today and so far so good. Upgrade cost from Win 7 is only $39 or €29 which is nice. Really liking some of the interface features/redesign. Everything seems pretty snappy, but this is a brand new uber box so everything is fast on it. Some of the MS online services seem really slow/unavailable tonight though.
Not perfect, but nothing ever is. I'd take this OS on a tablet or Phone over iOS any day.
