I know this is slightly old, but I just wanted to comment. I had a CFW PSP 1000 back in the day and loved it to death, and have many fond memories, and also probably some damage to my hands and wrists because that thing had shit ergonomics and weighed quite a bit. When I went to sell it on Craigslist after not using it for a while, I was amazed at how slow it was compared to, well, anything else I had been gaming on since, most notably my Xperia Play. Load times can be crazy. IIRC PSP 1000 had only 32 mb of ram for chrissakes.
At this point I think a PSP is only good for emulating PS1 and playing legal PSP backups on. Anything else and you have better alternatives.
