something that s gonna last because though ive been a fan of sansa brand mp3 players theyve just been so dissappointing to me of late especially the 250 and 240 models that i had been using and which all 4 of them ( yeah 4) crapped out on me. the screens wont work so you have to guess what youre going to play or the sound jack stopped working altogether so i figure its time to take the dive into the higher end of mp3 players. so any suggestions would be appreciated. ive been noticing the zune of late but i want to know ahead of time do they limit the music you can use on it ( does it have to be liscensed music).
