My 16GB iPod Touch has an irritating habit of momentarily freezing and then dumping me out of whatever I'm doing and back to the dashboard/main menu (whatever it's called). One vaguely reproducible way is to scroll very quickly through either album or artist view in music, and an almost foolproof way is to be listening to music whilst browsing webpages on Wi-Fi. Is this merely buggy iPod Touch behaviour that everyone's getting, or could something be wrong with it? I'm assuming the former, but I just wanted to check. It's all up to date, as is my 10.5-running Mac.
