Ok, I have to say it took me a while to find something interesting in Windows 7. But, in the tray, when we have some applications in there, there is an hover effect now. But, where it gets more interesting, if when you hover over WinAmp, or maybe other similar applications. Additionnally to see an overview of the running application, we get a toolbar where we can pause, play, etc.
Pretty cool!
BTW, on 64 bits with 8 GB or RAM, on Quad Extreme, wow! This is rocket speed!
