Can't say I get the overt angst. I get the frustration but not the angst. People talk about quitting Apple, this is their worst experience. Firstly, how many people waited hours in line for an iPhone? How long have you waited today to update this stuff? Secondly, if you're posting here and trying to do it right now, you're a little more than a casual Mac user. Deal with it. It's launch growing pains that happen with the launch of everything anywhere; this is just virtual rather than standing in line for hours.
Breathe, relax and it'll happen. Eventually. Probably after many tries.
You obviously dont rely on your phone for business and have to have it on pretty much 24 hours a day. Yeah I have waiting in line for HOURS for a phone. The very first Iphone, I got it, took it home, and waited for 24 hours for freekin Itunes to activate it....so yeah I should have KNOWN better, as we go through this crap EVERYTIME Apple updates ANYTHING.
This is what is causing the angst. THe days of a "Casual" cell phone user are long gone....this is a business device for 80% of us.
