It's not the fact that W8 is different that's killing it, it's that they tried to have their cake and eat it, too. They should have thoroughly designed a single new UI that harmoniously allows for multi-window, task management, and touch. Instead, they got lazy, made a UI for touch, and then stitched it onto the old thing. Not including the app store, Windows 8 is better than Windows 7 under the hood. They were brave enough to completely ditch their old UI with Windows Mobile, so why the hesitation with Windows 8? If you do a good job with the new UI, there's nothing to fear. The UI on WP7 was fantastic..how they missed with the desktop is mind-boggling.

I want to like Windows 8, but it's so visually and functionally jarring within itself; split personality. I hope they return to the drawing board for Windows Blue and do it right.
