Don't you laptop users get annoyed at how hot laptops get? I can't stand that.
I've used both, and it's not really a one over the other thing.
Both are good for different things.
You can, with the money, get a laptop that is very competent gaming wise (per mine), and while you can always get a more powerful desktop for the same price, the fact that I can play EaW, WiC, The Witcher, and any number of other games at school makes it better for me.
