I really like my unrooted NC. I use it primarily to check my email and to surf the web in a hurry (when i don't want to turn on my regular PC). It's great for getting weather forecasts. Also good for checking movie reviews while checking my cable system for what's on On Demand and things like that.
However, I do not at all like it for reading books. I find the screen very tiring to look at for long periods. So, if I had bought it to use as a reader, I would be disappointed, probably enough to return it.
I have a Classic Nook (e-ink), and that's what I use for reading. May get a Touch one. Have to restrain myself...
