I'll reserve judgment until I lay my hands on one.
However, I think it's critical to keep in mind that this is a "Rev A" product by a company that knows books, but has never made anything like this before. To me, the fact that it doesn't instantly catch on fire shows that they're doing something right.
I.e. I don't expect much from the 1st generation nook, but I'm fairly confident that the 2nd gen will be much better. Perhaps even some firmware updates will help fix the issues.
