Most of them are hacked/fake memory. This hacking will cause the problems he outlines. If you format, you will find much less memory. Probably about 2gb for a 4gb player. That plays movies on a 2" screen. With radio, voice memo, GOOD mp3 playback, folders, photobook, USB pen drive, speaker, changeable battery, earphones. For about �12. DELIVERED FROM HONG KONG. �12 is the price of many earphones.
I know the �200 160GB Ipods look nice. But the earlier ones DID have a ton of battery/screen problems.
I'm very happy with the hong kong one I got off ebay now that I formatted it.
