Media player seems far better in this OS than OS2007 (so far--limited testing).

A video that I previously could not watch using media player ( too choppy ), which required Mplayer for satisfactory/smooth viewing, now plays pretty smoothly in Media Player........and the audio come into my left ear's bluetooth headset too, nice.

I like the skins ( UI ) in 2008 better than 2007 also. Scroll bars are easier to grab, text looks crisper, more readable.
