Oh, not a kid anymore, sorry
In that case I'd probably pick the 15" Macbook Pro. The prices in the JB special are only $3 less than Apple's but they are the current models.
The new Macbook Airs have a very strong bling factor and are damn tempting, but the Macbook Pro is a far more capable and versatile laptop.
EDIT: Oh, and I'd get it from Apple so I could get the anti-glare screen. I hate those shaving mirrors…
Cheers
