even though i think windows is wrong by not unpleasing users with design changes for the better... and not agreeing that white space may be ok to separate the tag list and the message, there's no excuse to: 1. the buttons without labels. your user WILL have to hover the mouse every time he forgets one button. 2. the fact that it moved from a huge clickable area to 17x17px button to see the message headers (and that the header information was vastly reduced) maybe some huge user testing proved those right... but my constant cursing says that at least a 5% exist.
