Yup I agree with you. I seldom used the inbuilt camera, but I
still do, sometimes. As for mp3 playback, I find it totally
obsolete coS I've got an iPod mini. The phone's music player is
useful sometimes though, when you're in a group, and provided that
the environment is quiet.
As for the games, I don't think it's for showing off on the MRT.
Sometimes you do get bored on the train or on the bus. Even when
there's no one around, you still do play the game right? So it's
not for showing off purposes.
