If you wanted it for school, to take to the library for assignments and other such things, I'd say sure.
If you want it for gaming, no way! You'd have to get a MacBook Pro ... those are expensive.
My suggestion:
For a portable computer that will be used for school work and other simple portable computing needs, go for it. Gaming... no. To run decent games, you need a discrete GPU and that is in MacBook Pro land. Stick with the desktop then. If you wait a few years and get a computer when it's college time, then get the top of the line MBP.
Besides, by then the interest will be almost enough to let you get it. (Think 3 month rolling CDs)
