Query: great if not limited MP3 player

The pocket concert provides the following qualities - compact, rechargeable, easy downloading, easy to use, and so far reliable. The car adapter works very well for spendthrifts like myself who don't buy new cars or car steros. On the downside, the headset is poor quality and uncomfortable. Memory is not upgradeable but since it doesn't have moving parts, the system is skip proof. I use it for working out or working around the house. I did have some driver issues after upgrading to Windows XP. Intel's website has all of the upgrades but it took about 6 hours for me to finally get it right. I haven't had an issue since. With a better headset, I would have given it 5 stars.
