I never thought I'd see the day I say this. But Vista's new interface is very impressive. Hey, I'm only giving credits where it is due.
I actually agree with you. The attention to detail (note the glow on the window buttons actually *starting* in the middle and moving outwards!) is simply stunning. The new alt+tab behaviour is cool too, just like the taskbar previews. Another noticable improvement is that when an app hangs, you cannot paint it's window anymore. Really cool!
Of course it remains to be seen if all this actually makes it more usable.
