If you get it, how serious are you going to be when you test SteamOS, the machine, and the controller? For example, which one of these sounds like something you'd do?:
1. "W00T I GOT IN! Time to brag about it and marvel at it!" 2. "I'm going to play games normally and make note of anything I like and don't like." 3. "I'm going to play games normally, but I'm also going to go out of my way a bit to try and find problems." 4. "I'm going to take full advantage of it. I'll play it, mod it, hack it, and write about it."
Also, would you keep this board updated with your experiences? Post pictures? Videos? Things like that?
What else would you do if you got into the beta?
Personally, I'm somewhere in between number 2 and 3, and I'd try to keep this board updated with my findings.
