S.H.
The reason for a DVD drive in a computer, is also not only for games, but some people still save things on it etc.
There is no drive in the Airbook. So to save things, he needs to use a Thumb-drive etc.
For serious gaming anyway, its best to just have an Xbox etc.
Not a computer.
A DVR drive anyway, is getting outdated. Computers nowadays will not or do not, have it.
Anyway, yes, a MAC. But, think ahead too. He will use it for: 8th grade, then 9th, then 10th, then 11th....? and so forth?
My Mom has the Macbook Pro.
Go to an Apple store, and ask them, what is good enough for a High Schooler.
Or what is better... for a High Schooler.
