At first I though that the random re-boots were being attributed to me rooting the NC. (it was tough to compare if it was the rooting as I did that on 2nd day of ownership). After a while this became worse as I noticed that my NC was shutting down or re-booting anytime I touched the screen or just the frame in the upper left corner. I uninstalled the rooting and reset the NC to factory setting (then updated to 1.1). The strange rebooting continued... What was 1-2 x per evening happening turned into every 15-20 minutes annoyance. After I called B&N customer service yesterday and some trouble shooting over the phone a conclusion was made that my NC is faulty and they are sending me a new one (already have the tracking number) I was wondering if there is any pattern for this problem or if you had to do a return / exchange for another reason ?
