need advice from people who have a quite big expierence on mp3 players. I have no exact requirements, but want to know what choices could be the best. 1. sound quality 2. battery replacement 3. durability 4. measurements I dont know yet, what would be better.. 1GB flash, or bigger HDD player. To be honest space isn't the most important thing to me, but of course everyone wants to have more space. I dont have and price limits, as better once to pay more than by cheeseparing and pay twice. Everyone who can give the best choice and small reason why he thinks that player is the best, are welcome. PS: all who care just about display color & shining buttons, please do not replay. Thanks.
