1. Portability
The main feature of the PSP is portability. It can basically hold all types of media in your pocket. You may watch videos, view pictures, and play music, and even play homebrew. I consider the portable games just a small plus to this.
2. Good Graphics
PSP's have basically similar or better graphics than the PS2
3. Music
Thousands of songs you can fit in your pocket.
4. Movies
Watch full feature movies or just homemade videos wherever you go
5. Pictures
Store 1000s of pictures on a single memory stick. You can even get a camera accessory so you can take pictures yourself.
6. Wifi
Play games such as Socom wirelessly with people around the world! Even browse the internet with this small console.
7. Homebrew
Homebrew. One of the main reason people buy a PSP. You can play custom made games and applications to expand all the functions of a PSP!
