I immediately like it better than Vista Start Menu, mainly for the fonts (better) and use of cleartype font smoothing, so now fully supporting more recent versions of Windows. Also that it is natively 64 bit. Would like to see a bit more customisation available of course, mainly more skins (hate the blue background on the only existing skin) and I'd like to be able to easily create new entries in the menu on the left. Haven't figured out what Groups are for yet.
