don't see whats wrong with a PSP,
just a thought, on the PSP the "inbuilt" memory was for essentual system files and if changed or deleted you could "brick" you PSP, so just thinking that the GP2X inbuild memory was kinda the same, tho you can't acually see the inbuilt memory, its like a flash thingy inside the system you can't access from outside the machine, only bad code you download into the PSP deletes it and u have an expensive doorstop.
