Did Vista ship standard with version 7 of IE? It's nice to have a big vendor start to force the clueless to update, but IE 7 is also still a big POS. The fact that IE in general is lack-lustre aside, IE 8 just works better with all the CSS I've ever had to develop (for starters).

MSFT should really have insisted on updating IE6 to one of the newer versions in one of its many security updates. Most customers blindly update all their other MS stuff.
