My dad had a MacBook Pro at first, but he broke that, so got him a MacBook Air; that was 3 years ago. He does the basic stuff and that's it, so it was a perfect choice.
Anyways, just replaced it with the latest 13"; he's liking the faster speed (seeing his old one was the 1.6/2/80 model and the new one is the 2.13/4/256 model); the SD slot is nice for his photography needs and the added screen resolution is good.
