I searched "nook" and it seems as though nobody who ordered one has received it yet.
Be very interested to see how it stacks up. Looks good, but not enough better to change now. I may mosey down to B&N to see how it handles.
I checked a few newly released books on Amazon that were over $9.99, and about half of those were $9.99 and the rest around the same as Amazon. Looks like book prices will be a wash.
I'm still lumbering along on a K1 and perfectly happy. I see that the nook has both an SD slot and a replaceable battery, so that puts it ahead of a K2 in my estimation.
As far as I can tell, no folders.
