I think someone posted that it would be a good idea to wait until the second generation to get any kinks out of the way.
I admit to having an itch for one, but since Apple doesn't do Flash I couldn't justify it. I have two developers who were going to the Pentagon City store yesterday and I was going to go with, but things got busy and I just couldn't. They were the ones who alerted me yesterday. Now I'm home with a sinus headache and I'm going on the web and there seem to be some issues - not enough to be a disaster but enough to clog Apple's forums, it seems.
No one here is having any problems, but there may be new folks...or new to Apple anyway.
