I too wonder what readers they polled. And if 10 books a year is an avid reader then I must be a rabid reader.
Guess I'm not at the point of of not preferring my e-reader (2 years owning one) I much prefer reading off my e-reader. I am getting upset with how the prices are going up though. I will not buy an e-book that costs more than a paper book. And I won't buy the paper book either. The only paper books I have been buying are ones for my book club & only if I can't get it in e-book.
I don't feel I'm jumping through hoops with the DRM, but then I have a Kindle & a Sony so I haven't had a problem. And so far I've pretty much find what I want to read..in fact too much.
