Aero Basic (or the non-glass mode) didn't hold me for very long. It was... boring, compared to Aero Glass.
A co-worker of mine complained the other day that Vista is forcing him to not maxmize his windows. Why? Because maximized windows in Vista become opaque, and frankly, glass is too sexy. Yeah, he has issues.
Glass is sexy though. I do notice that I don't immediately maximize windows as much as used to. Maximized mode is nowhere near as good-looking.
Translation: Glass rocks. Nicely done, guys.
