Why isnt my PSP more use?

OK, so the PSP is in theory an amazing little device,  widescreen, wifi enabled blah blah blah, ive had mine since they were first released….. but…. I just cant figure it was the cool device I hoped for….  I bought a 512MB card,  and I know I could waste a load of money on a larger card now…but all in all the PSP is just not the cool device it should be.  I think m problem is that im not that into games, and its not the all kicking multimedia device I ever hoped.
