there's a lot of conflicting opinions about which PSP model is the best, 1000, 2000, 3000, or GO. after spending hours reading reviews on the net i ended up buying All 4 different PSPs. so here is my thoughts on the matter. for me the 3000 and GO are TIED. the X000's are pretty much the same except for 1.Hack-Ability, 2. Screen quality the 2000 screen has ghosting, 3000 has Artifacts, and GO appears Smaller. there all shyt. well screen artifacts arent nearly as bad as Ghosting, IMHO. and the Temporary CFW, Pro-B7, is actually Better than ME-6 because you can switch to OFW on the fly, its the best of both worlds. and really, it only takes 2 seconds to load CFW, i dont mind loading it every time. but i still want Bluetooth PS3 sixaxis, Pause function and a Button Cover when im on the Go. i wont buy M2 cards just use the 16GB onboard. and UMD Support means absolutly Nothing to me. so ill keep my PSP-GO, for a portable, and i have my 3000 permanetly plugged into the Plasma TV. if i handle the 3000 with kid gloves it should be fine. so between the GO and 3000 i have a perfect system. (think you cant tell difference in screens? play Dungeon Explorer on 3000 and 2000) the PSP-1000 is a beast, its huge and weighs a Ton. it has Less RAM, the D-Pad is not as good, and the screen is worst, its almost black and white compared to 3000. but it may be easier to find accessories for it. also you can remove and replace the analog nub, somewhat useful, but who cares. the PSP-2000 has the distinction of being Fully Hackable and Pandora compatible. its more durable software and hardware wise. but the screen is not very good compared to later models. the PSP-3000 is very delicate, hardware and software wise. i bought a brand new 3000 which had a Stuck/Dead Pixel out of box! unnacceptable. and the casing feel really cheap compared to older models, i can almost hear the plastic creaking when you hold it. now the paint is starting to peel off. and if you Brick it your screwed cause Pandora battery isnt compatible. But the SCREEN is the best of all PSP models. its so bright and vibrant it makes the 1000 screen look like a pile of puke. the PSP-Go cannot really be compared to other models, because of the battery situation. its great for the daily commute or for waiting at the DMV, but if your going anywhere Long Distance, you want to carry several extra batteries. it could really be seen as a cheaper iPhone alternative. because its smaller but not serviceable, you'll never take it apart and be able to put it back together again or even install a new battery. thats where it loses points. another problem is the AV out Port. you cannot use TV Out and charge it at the same time because they use the same port. and it uses M2 cards instead of ProDuo, so you cant use Cheaper ProDuo cards. on the other hand, GO has 16GB built in and its exactly the same price on ebay as a beat up 2000 with no memory. the GO also has a Pause/Resume Game function like savestates for psp. and has Blutooth, so you can play it with a PS3 Controller. i Absolutely Love the Design / Layout of the PSP GO. More Gameboy, Less GameGear. i hated the button layout of old PSPs because the analog was too close to Down and Home buttons, i kept hitting the Home button at crucial points in the game. and i like the go's "Clicky" buttons rather than old "squishy" buttons. and the analog is now right in the center, perfect thumb length. and the best part is you can Flick it down and have the precious analog protected at all times. now, the Go screen is a point of contention for me, i know its the same resolution, i know its brighter, i know it dosent suffer from the ghosting of 2000, or the artifacts of 3000, but it just seems so damn SMALL. i dont know why, but i always reach for the 3000 when im at home.
