DarkNight_DS beat me to it.
Thats one of the reallly nice things about steam. Once you register a copy its yours to redownlad whenever you want. I tend to unistall games after I beat them. I uninstalled HL 2 after I played it and reinstalled it to play back throgh it before playing episode 1. I thought I was screwed when I got to disc 4 it had a giant scratch in it. Steam picked it up from there and finished the reinstall.
I'd buy it on disk if you have sucky dsl. It took me all night just to download episode 2 on 1.5M(500k actual).
