I recommend the PSP.
It is a great handheld tool, music, videos, photos, games, internet if you ahve a wireless internet connection. (web browser)
I love my PSP. It has saved me boredom on long road trips (we drove down to New York one time and I live in Edmonton... my PSP saved my life) but anyway, by all means, get a PSP. They have gone down in price significantly, and it is a good investment

only bad thing, I like to update it frequently but at the same time want to try out some homebrew programs or games and I have the most recent version... oh well I'll just have to buy my own games the LEGAL way! >_>
