sound is great. the bottleneck is the earphones of course, but they perform well for in-ear buds. the cell phone uses memory stick duo cards, so the phone will hold as much as the card will.

a 512MB card was included, as well as a usb2 cable (thank god). phone recharges when connected to the usb cable too.
i'm very impressed with the camera too btw. good enough to actually start using it on trips and quick snapshots. nice optics.
