@francetales: the problem is Windows Media player not the sd card. Try Pocket Tunes or some of the other players that work much better and remember where you keep your music even on memory cards. Newer versions of things like Pocket Player are also very finger friendly.

Start up speed is great, although I bet once add-ons start piling on, it will slow down. Page rendering is decent, although I'm getting quite a few crashes and it doesn't play nice with some things like Facebook or Yahoo Mail... grr.
