80GB iPod, PSP, or DS for B&M's?

[AABCDS]

I used to be an exclusive online $25 and $50 PLO8 player and am trying to make the switch to LO8 live. I've played less than a dozen times and have been bored to frustration live because I used to multi-table.

I've been researching the 80GB iPod and the PSP am having trouble deciding on one. After accessories and media, the prices are comparable. Each have similar media capabilities such as music and movies.

One aspect I am concerned with is the ability to hold my attention over many sessions of poker. I think I would have to give the edge to the PSP because of the large number of games available. iPod games are limited, although iTunes does have Scrubs episodes. A season would cost a little bit more than a PSP game and would give 8 hours of entertainment, less than a video game.

I haven't done much research on the Nintendo DS but some pros are the price and Final Fantasy 3 and cons are that it doesn't play music and I haven't found a way to extend the battery life of the DS to last for a long session of poker, 8+ hours.

Which one would you rather have? Maybe you own one and would like to discuss its pros and cons.
