I'm gonna buy a PS3 but I need help!

[lightbleeder]

I wanted a Wii but as they are sold out so I will buy a PS3.

I'm planning to buy a 40GB PS3 but I have a doubt.

Are there other differences between the 80GB and 40GB PS3s than:

- The 40GB difference

- Motorstorm

- PS2 compatibility

??????????

Please help!
