If you're going to see any information, they better be transparent rather than translucent.

OSX has had translucent effects for sometime now. Gates is always trying to play catch-up. By the time Vista comes out, Apple will have left Microsoft behind in the dust. With the Mac Mini available, there's really no compelling reason to wait for Windows Vista. The future is already here and its spelled U-N-I-X.

Vista and Mac OS X both support transparency/opacity for windows, menus, etc. in their screen compositing engines. Vista uses too much translucency in their window frames, in my opinion.
