It seems Aeroglass gets dumped at the slightest hint of being asked to be backwards compatible. That's going to be pretty unavoidable with the way M$ are (ab)using the graphics system!
Considering that we're writing games and they run in full-screen (99.99% of us anyway) this isn't going to be a problem.
Same with OpenGL. M$ are crippling it severly in their current build of Vista, but if you switch to fullscreen you don't have any problems. What we do get is a speedup over XP because Vista will supply the capability to disable major portions of the OS as part of your game startup, freeing up many more resources than XP is able to do.
