I just bought this player and can't say enough good things about it. Expandable memory and integrated USB connector is what attractred me, and rechargable USB powered battery. I had a Samsung YP-U2 series that has a similiar design but it lasted 3 weeks and wouldn't power up, it also had many problems with Windows Media Player 11.This SanDisk is perfect, I've only had it a couple of days (Best Buy had it in stock first) but I expect it will last longer since all other SanDisk products I have bought last a long time. Some site list mini SD as the expandable memory, but it's micro SD (this site has it right). For $60 you can't beat it, it does everything right. iPod who?
