Hardware improvement suggestion: Bluetooth
It would be nice if Sansa clip has bluetooth since it already has a built-in mic for recording.
one of the inconvenience part when listening to MP3 players is that your ears are occoupied by music.
so when a call comes in you either miss the call or you have to pause the music, take out the phone, take off one of the earphone, and then you can answer the phone call.
I bought a Philips LUEX MP3 player with bluetooth recently. it is great, but it does not have resume/bookmark function for music, so I have to start over from the beginning everytime I turn the unit back on.
