Yes, it's been out for a few months. The only thing about it is that they made it so small that you can't really read anything. That is why I like the second one more.
Hmm...Seven transformation pack? looks interesting. But it could be very hard for Windows X, even they use their concepts, the whole GUI of Vienna looks farther from the previous version of Windows. I think Windows X will work for it if the Microsoft show the real appearance and GUI of Vienna, I think it could be the next project of Windows X. booyahcomputers has a point on it, well we will wait for it.
BTW I think the better name for seven transformation pack is "Vienna Transfromation Pack" hehe...
I meant that they would use the concept pictures, bc.
Well, I think some of the things could be implemented, like pie menus. There already is a plugin for firefox that allows it to have pie menues. http://www.radialthinking.de/radialcontext/
