12" does not have L3. You know, if you are a student, you could get a 12" powerbook for over $1000 cheaper. I went that route. The 12" comes in supporting airport extreme and bluetooth builtin, dont forget.
As far as video goes. I can play WC3 without any hiccups on my 12" with only 256MB RAM.
There are a bunch of rumors that Apple will be announcing the new 15" al books soon, but they are just rumors.
Don't get the superdrive, its overpriced and its only a 1x burner. Pay $150 and get a 4x burner for your PC. It will save you some cash.
