My wife has the music Xpress and it is an okay phone. The music playback is great, not as snappy as some media players while browsing through music, but great shuffle and some good playlist options.
A few complaints though, speakerphone sucks, battery life goes quickly as the device ages. After 1 year she is lucky to hold a charge for the whole day. The SIM slot is kind of iffy even with a new card. The audio jack is 2.5mm (easily remedied), and texting on the slide out keyboard sucks.
