If it makes you feel any better: I have been signed up since day 1 of opt-in (plus doing the opt-in redo when they made that blue post requesting people do so), I have a fantastic computer, I have every game that can be registered to a B.net account (except WoW expansions), and I am not in the beta...
Whereas I only have an inactive WoW account (over a year inactive) and StarCraft 2 on my account, haven't played SC2 since the first week of it's release.
