I was hoping that iOS 5 would be available before I had to leave for work. It was not. I will not be back home to connect to iTunes for another 9-10 hours in order to download from there. How much hassel would be involved in trying to install iTunes on my work PC downloading iOS 5 while at work and then still being able to use my home Mac again from that point on? I really would like to down load this new OS but don't want to screw myself too much. The main reason I want iOS 5 is to get away from being tied to my home computer.
