I will never use Steam again. I'm an avid gamer, but one who is cursed to use dial-up as my gaming medium. After buying three Steam games, and getting screwed with all three, I decided to forgo Steam forever more. Especially after a customer service rep told me that my ambitions were pointless - Steam has a dial-up compatibility mode, but it's mostly for appearances. The rep informed me that Steam doesn't (and probably won't) truly support dial-up.
So no more Steam for me.
