....I can't believe I didn't realize that was a "concept" video
I did see that someone had some speculation about windows 9 may come in different flavors such as tablet version, laptop version, desktop version. Kinda makes sense, when I saw 8 for the first time, mainly the metro screen I thought to myself...This belongs on tablets and phones...things that you have a touch screen that you can swipe with. Touching the corners, swiping the metro all made sense for touch screen. That's how it looks to me at least, looks like the non-touch screen users were an after thought and they were like "yeah lets give it to them too...change the metro ui for them? the hell with that, lets get this thing shipped already! Bill gates needs an aircraft carrier by Christmas!"
The guy did mention a strange pattern
Win ME - didn't do great
Win XP - awesome, solid OS
Vista - didn't do so great
win 7 - Awesome! solid OS
win 8 - not doing so great, confusing standard users
win 9 - ???
