Thinking of buying a PSP ,,,Have a few questions.

[Reasonable]

For mivoes I use DVD Decrypter and PSP Video9 to first rip DVD then convert to format that PSP will play.

Make sure you get new lighter model (just in case any older ones are still kicking around).

Myself I have a 4 GB card for storing movies and another for games, music and images.

Fun games are Daxter (still one of best PS games I think), Ratchet and Clank, God of War and Locoroco although there are many others from most genres.

As for PS3 / PSP you have remote play, ability to stream content from PS3 to PSP over internet plus ability to copy (suitable) games and content back and forth.

You can also surf internet with PSP, search google and use internet radio.
