Edit--
To follow up. It's been about an hour since the computers came back up in the terminal and I'm finally in my seat on the plane. About 3 hours after it was supposed to depart.
There were several canceled flights in my terminal and no other flights going out so people had to stay overnight. Most were very mad as American was not supplying food or hotel vouchers - all those people are coming out of pocket I guess.
I heard quite a few saying things like, "No wonder they are going out of business" and "I will never fly American again no matter what".
