PSP Slim. Should I get it?

PSP is awesome. You can put all types of homebrew on it and you dont have to buy any games. I d/l all of mine off the internet. Plus you can put an emulator on it and play other game systems, like PS2, Sega, N64, etc. Im not sure if they've done something to the new ones to prevent them from doing this, though
 
iPod also uses MPEG4. If you use an application like HandBrake to convert, there are presets for a lot of different devices.

If you are converting DVDs, a lot of newer DVDs are copy protected to keep you from ripping them; it took me forever to rip Casino Royale, and I have not yet beaten Ratatouille.
 
I just LOVE my psp. it really kills time at the airport, long car rides and just about anywhere! they have the cutest baby pink and lavender slim psp's that are japanese imports but you can find them at some places . I just got the lavender one last week at a japanese video game store and i LOVE it, it is SO cute!!
