It's kinda important to note that there were no new functionalities demonstrated there, it's purely eye candy. Multiple desktops, windows snapping against each other, animated previews in the Alt-Tab window are all standard parts of the modern KDE/Gnome/whatever experience. The Docker launch application *is* a plain Mac ripoff, no matter what the author says to the contrary (http://www.xiaprojects.com/www/prodotti/kxdocker/main.php) ;) Also note that the eye candy demonstrated requires x.org X11R7.1, which is still hot off the presses and not standard in many Linux distros. It's not supported by default by either ATI's or nVidia's binary display drivers either, although it seems that nVidia is almost ready to release a driver with 7.1 support. It will probably be another 6 months before displays like the one demoed are common, to get them right now you need to muck around with specially compiled software etc. I use Linux 90% of the time, and Windows 10%. I think that KDE on Linux (even without Xgl) can match Windows XP for eye candy, but really, do you even notice it after 10 minutes? The important thing is whether the candy gets in the way of productivity, and if so, can it be turned off?
