When it started to go wrong on my 3G, I searched for tips about the Error -34 I was getting. This doesn't seem to be the common one, but there are plenty of people having problems.
Buying Apple stuff is a compromise, like all such decisions. But what you expect is a very smooth user experience, so you don't have to worry about the technicalities. This ain't happening this time, for me or a lot of people. So, I'm sure at some time it will get all nice, but WAIT.
Yes, I know I should have known better, but I thought it had been out for about 24 hours, and the stories ought to have been appearing. Where were all the Apple haters, when they could have been useful?
