1, 1000 feels much better than 2000, but the difference lies in the protruding part of the back, which was omitted in 2000 to reduce the weight ... 2. Thin P seems to save more electricity. 3. The screen difference is not big, but the thin P is slightly larger, so you can know by comparing the two groups. 4. Hardware, 2000 has 65438+. Let some simulators run more smoothly ... nonsense: 3000 memory is also 64MB ... I ... personally speculate that PSP games may use 2000,3000 extra 32MB memory in the future ... 5. Thin P has video output function (and color difference line = =! ) It's useless for ordinary players. If you want a big screen, it is more convenient to use USB to input the computer ~ 6. Thin P has many colors for you to choose from, while fat P is much less. 7. In terms of brushing, if the risk of thin P and fat P is 3000, if you are not a game controller, you don't have to wait. The promotion of 3000 is not very big, but you have to wait for the motherboard of 3000 to crack, and then wait for another month = = 300. There are 1 2 3 generations here, and the differences are clearly listed at http://www.emu-zone.org/html/handheld/PSP/20080821/25243.html.
