I always have at least 2 mp3 players with me, my PDA loaded with games and/or videos, my gb micro with several games, a digital camera, and a cell with tetris. I make my own downtime.

Did not work (froze on loading screen):
Dane-Elec 512MB (can read files)
Kingston 512MB (cannot read files)
Canon 16MB (act of desperation)
Did work:
Sandisk 1GB
Formatted to FAT32 in xp, copied kernel file first, then the rest of the files minus the boot file and finally firmware upgraded in...
