Can you count to 3 ? J/K. If you want to know differences your best bet is to search it. Look at wikipedia, they have pretty good comparisons there. Other websites might also help. But basically, you want a 3000 or PSPGo, IMO. PSPGo only works with downloadable games while 3000 works with UMD or downloadable (requires memory stick).
difference between PSP 1000 and 1001
There's a difference? Never heard of this
difference between PSP 1000 and 2000
the 2000 is slimmer (because the underside is flat) the face buttons and dpad is better, the nub is slightly better, the start/select buttons are easier to press, it has shorter UMD load times (because it was made by a wizard), and the UMD disc door is different, and the screen backlight is slightly stronger. 1000 is heavier and is also said by many to have a more quality and durable feel but do not be fooled, the advantages of the 2000 far outweigh.
difference between PSP 2000 and 3000
the 3000 has a more vibrant screen meaning brighter but also richer colors. Other than that they are basically the same. 3000 also has a microphone built in. Start/select buttons are a different shape. 3000 is also slightly more curved in shape.
difference between PSP 3000 and PSP Go
Go has totally different shape and size and form factor from the other 3 PSP models, and a different feel to the buttons, dpad, and. nub. The start/select button placement is totally different. It is also smaller and has a smaller screen. The PSP Go does not have a UMD drive so all games must be downloaded from PSN. (which all previous PSP models can do anyway) Also, the PSP Go uses different cables and connections from the other 3 PSP's and different format for memory sticks as well. (''memory stick micro'' instead of ''memory stick pro duo'')
My version of the PSP Go:
- The design of the system isn't very helpful for long complex games like Gods Eater Burst and Monster Hunter series, I get cramps at times
- There is a lack of games on the PSN store and are more expensive than what you can buy in-stores as a UMD
- You would have to buy M2 Memory cards which are generally more expensive than the cards you can buy for other PSPs
- Overall: The system, games and memory are more expensive than its predecessors
- The system is smaller/lighter/easier to carry in pockets
- It has the most features such as bluetooth support which other Psps lack
- Games bought in the PSN can then be used for the PS Vita once supported
- It has the sharpest picture compared to the previous models
- Has a clock/calendar when closed
- Has a built-in mic
