Windows 8 — Disappointing Usability for Both Novice & Power Users (Jakob Nielsen's Alertbox)

Windows 8 — Disappointing Usability for Both Novice & Power Users (Jakob Nielsen's Alertbox):

As it turns out, users didn't mind horizontal scrolling on the Surface, which is interesting given that horizontal scrolling is a usability disaster for websites on desktop computers. Still, there's such a thing as too much scrolling, and users won't spend the time to move through large masses of low-density information.

Nielson gives a quite damming review of window(s) 8.  Good UI read.
