I have the 2GB that came with my 9700 still. I didn't want to transfer everything over to a new card. Plus 2GB is enough for me. I only keep about 100 mp3's on my device. I like to use Pandora for music.
The Class number defines the spped of read/write operations. The higher the number, the fatser the card and, of course, the more expensive.
Class 2 cards work perfectly well for playback, how fast do you want to listen to that MP3, but the real benefit of higher Class numbers come when you plug the microSD card directly into your PC and copy to and from the card.
