Apple's laptops are undeniably the best... and the 12" powerbook w/ superdrive is awe-inspiring:

And you can get that for $1699 from the Apple educational store.
I'll admit the thing isn't the premiere gaming system, but it's 4.6 pounds and it has up to 5 hour battery life. Also, it has a CD-RW and DVD-RW combination burner. Try one out... they're awesome.

That's a russian web URL. I wouldn't buy from that place under any circumstance.
