"It's different" is the primary thing I hear. I'm a network guy and I learned rudimentary v6 in college ten years ago. I'll be the first to admit I don't know as much as I should, but give me a day and a good resource and I can easily be back up to speed.

My boss on the other hand....."man, it's just so complicated, I hope we never change".
