Taskbar
I know this is only a beta but compare Vista and W7's taskbar and I think, aesthetically, Vista's wins by a long shot. First of all, the start button in Vista just looks like it fits perfectly right into its little slot and in 7, it's just kind of "there". The other thing, is that Vista's looks so sleek and 3D while 7's is flat and quite boring. I don't like Vista much but, it hands down wins the best looking windows award.
EDIT: Another thing is the show desktop button at the far right. I think it either should have an option to remove it or make it stand out less and go along with the look of the rest of the taskbar.
