Amazon had the nook WiFi here very quickly. I could get started on my own without too much trouble. I did go to Barnes and Noble a few days later and got plenty of help from the Nook man there on the finer points. I have been using it since Father's Day and I really enjoy it. I also enjoy going back to the Barnes and Noble store and reading some of the books there on my nook free of charge.
