Sounds like "cockpit error," to me. I haven't experienced any of those problems.
I'm curious to see how many people purchase an ereader and then complain because it's an ereader.
I think what you are seeing is the pervasive influence the iPad has had on the eReader marketplace. I can't tell you how many people I've met who bought an iPad PRIMARILY to use it as an eReader and not a true tablet ocmputing device. People expect eReaders to perform iPad-esque functions because the iPad can perform eReader-esque functions.
We have a Kindle 3, an iPad and now a NC in the family. I really am happy with the NC given the fact that I can still tie my reading experience pretty seamlessly to web lookups for further reading/research. Yes, I know all about the "reader trance" and not disrupting it. But I love having a web browser deeply tied to my reading experience and the NC handles this just fine. I can understand why people would naturally expect richer browsing experience...after all, we are talking about a browser, the "least common demoninator" in apps these days. Everything can run a browser and there really isn't any reason why the NC's browsing experience can't be improved slightly.

I think it is also the influence of Android phones (and now tablets). Everyone knows the NC is based on Android so they are expecting that more of what Android phones & tablets can do will be available on the NC. By contrast, very few seem to be aware that the Nook Classic was also Android based.
Moreover, B&N has taken some shortcuts with applications on the NC. The PDF reader, for example, is not a full product and its user interface doesn't match the reading experience of the ePub reader. That is not what occurred in the Nook Classic and this has created a lot of user complaints.
Aspects of the NC seem rushed to make it into the Christmas sales season. I'm sure much of the problem will be fixed over time. However, there may be lingering problems because users are now comparing the NC's apps head-to-head with superior apps available for Android.
My husband bought me a nook color and I love it. It is easy to read books and I can use the web without any trouble. We bought it at a barnes and noble and not on line and there were alot of people there to help me get started. I am sure if you could go to one of their stores they would be glad to help you. Dont give up it really is a great e reader.
