Laptop, for me, affords far more flexibility. I used to be "sold" on having a Desktop, and still have one, but it's too physically uncomfortable to use. I've barely touched a Desktop in the past 6 years.

As far as overheating? I've encountered that with my Desktop, but not my laptop (and I'm on my second). My first laptop? The hinges - computer-to-monitor - cracked.

I luv, luv, luv my current laptop! It was a gift. It's a HP special edition, VISTA. Not had any major prob. with it from the day I booted the first time in December, I think it was.
