PSPZ is a combined hardware and software project with the aim of adding to the psp platform features that i believe should have been there from psp's launch.

Features such as:

1) full touch screen support,

2) increased battery life

3)re-designed control pad

and originally PSPZ had the aim of adding a fully integrated GSM phone but that part of the project has been dropped mainly due to the unpopularity of the idea!
