Reminds me of the Liandri Corp's slogan: "Liandri Brings You Tomorrow, Today".
I don't think I'm going to go for this. 2 reasons:
1) If you talk to say game testers they'll tell you they lost some of the enjoyment of playing the finished game because they recall it in its less than perfect state. I don't want my first impression of a game to be a glitch fest. First impressions last.
2) Discounts. Or rather the lack thereof.
Nonetheless I do like that Valve did this. Its progress & a feature even if I won't use it.
