We're moving all her files onto her own partition on my (ca 2005) 17" MacBook Pro.
I'm now on my new 15" Retina MacBook Pro -- CNC machined from three hefty slabs of aluminum. With its solid state drives, I fully expect it to be the last computer I ever buy.
As successor to the 17", we looked at one of the new MacBooks for my wife. Even though it is also machined from slabs of aluminum, it is clearly thinner overall than the Macbook Air -- and since it uses SSD, It will probably outlive her, as well.

Tell us again, how buying crap and junking it after couple of years is a "better value"...
Forgot to mention that that new, all aluminum MacBook sells for $999 at Best Buy...
