Ah man, 1 gig of mp3s on psp is a nightmare on its own. There are no set play lists or seperate folders. more than 100songs is not helpful. But if you have 1 or 2 CDs worth of music is fine. Watching videos with 1 gig is usful but not for music with the psp.
I dont judge the DS simply because I dont own one nor does its style of games apeal to me. I just dont need both since im not a die hard gamer, I do own many games , I just dont feel the need to own them all(xbox360)
