Does the PSP need a memory card?

Answer 1

The SONY PSP doesn't necessarily need a Memory Card to function. And by function i mean to play a game or use the internet but up to now SONY PSP's are sold with no internal memory which means if you want to have Pictures, Videos, Music, and save game data you need to have a memory card.

So basically you need the memory card if you want to use the PSP to its intended use.
