psp is a gr8 gadget .. i wish it had a phone built in .. hehehe
..
Go for the PSP, if you buy from Sony .. you will get the PSP 2.0 = PSP Lite and Slim
ya slim is better, the efficiency is improved but they have reduced the battery size, so as a result the same back time.
ram is double, with some extra tweaks, but overall its same. a better package now.
the only problem is the UMDs are quiet expensive.
if you buy a gray market product or change the firmware of the original psp .. the warranty is void./
