Purely a cosmetic issue, but I really think they should make the Apple logo on the back of iMacs a glowing white one like it is on the MacBooks. This wasn't much of an issue before when the iMacs had black plastic for their backs, but now that it's an aluminum unibody, the silver back looks exactly like a MacBook Pro's lid, and a glowing white Apple on it would simply rock. Much better than the plain black Apple we have going on now. Now I understand that as a desktop, a lot of us position our iMacs with its back to the wall, but there are also quite a few of us that don't, especially those who use iMacs at work. Couldn't hurt to add a white LED and make the Apple glow. The Apple on the front below the display should still be black though, IMHO.
