Hey, cool thread!
I've had:
Black 1000-I actually think this thing is sexy, and felt good in the hand, despite the sort of negative things about calling it "phat" or whatever.
Silver 2000-Daxter bundle. Hated Daxter, and it turns out I hated the silver color-looked cheesy and cheap. The color was the main reason I bought this! In restrospect I would have just kept my black model (sort of wish I still had it!). The d-pad on this was much better than the original though (which until this model I thought was the best ever on a portable). This and the 3000 have 'big' console quality controls, save for the stick (which isn't THAT bad and gets the job done).
White 3000-Traded in my 2000 for a white 3000 as I always wanted a white PSP, and hated silver.
Black 3000-since the 3000 is probably the final model PSP, I decided to buy a spare, so now I've got a black and a white one.
Regarding the screens...in 2004/05, the PSP's screen was just astonishing. As much so as the hardware was. It's still fine, but it's actually not as bright as the DS XL's are, and I'd love a higher quality screen. You can get better TN screens than the PSP uses now, and of course IPS is better still. I'd love one final PSP model that has a 4.3 or 5" IPS screen, and maybe a folding design (put the freaking power connection on the top of the unit so it doesn't get in the way while I'm playing!).
Anyway of course they changed the screen between the 2000 and 3000, but the 3000's is....different, not necessarily better or worse. I tend to leave it on "wide" or whatever the mode is, but it...I don't know what it is you see on that-it's almost like scan lines or something, except that doesn't make sense. I don't know what they're using, but I know even with TN screens you can do much better now. (though again, it's not unusable and I quickly get absorbed by the game regardless)

What kind of issue does it have? I can't remember if I've ever had a PSP game crash on me. Maybe, but so infrequently that I can't remember it.
