@Bas:I think it actually got noticed. Whether it would work today now that tech journalism has changed and social media has evolved I don't know, but maybe Long Zheng's site's credibility would help.
The whole fullscreen start menu is touchscreen oriented. Scrolling a mousewheel up and down to scroll left and right is ridiculous. Having to go into the corners and "swipe" away from it is definitely a touchscreen gesture, swiping from the left side to switch apps is made for fingers on a screen that has a screen that's flush with the outer bezel, not a mouse.
