Hi,

I wouldn't say that one is better than the other, but that PSP 2000 is an improved version of PSP 1000. The PSP 2000 is widely known as the Slim & Lite because is 33% lighter and 19% thinner than the PSP 1000.

Apart from the change in design, the PSP 2000 has a bigger RAM capacity - 64MB, has a TV output and can have as accessories an optional camera and a GPS. Even more, you can install and enjoy Skype on the PSP 2000.
