The app store became live at 1:59 central time. I placed my order, was thrown off by having to change a credit card quickly, but everything loaded smoothly. At the very end it timed out 3 times during the final part where it asks your password again. Third time it worked. I was shocked by how smooth it worked. Posting here from my iPhone, the computer hasn't been touched tonight. Success!
