Don't *you* customize your desktop? Because I sure as hell do, since nothing I've found works 100% for me out of the box: not Gnome, nor KDE - and definitely not Win7 or Mac OS X.
(It's AWN, not Docky by the way, check my post above for more details).
You must be kidding me, right? If anything, this looks very close to the Mac OS X dock or the Windows 7 taskbar.[blah] Windows 95 [blah]
Where did you see Compiz on that screenshot? There is absolutely no difference between the Metacity compositor and Compiz as far as that screenshot is concerned.Compiz doesn't count because it is not the default Gnome WM.
