So, I've been wanting TF2 for a while, but I've been putting off buying it for the PC since I wanted to buy the Orange Box for my 360 when I get it this fall. However, seeing as how it's possible to just buy TF2, I think I want to do that. Since I'm impatient, I was going to buy it here and download it:

But does anyone know how licensing works with this? I don't want to download something that will only have one license or only be able to install on one computer, since chances are I'll be reformatting my laptop from time to time, or building my own desktop in the near future.
Does anyone have any experience buying it this way, or know how online purchases usually work?
