I am a ferocious reader and I absolutely love books. That said, hacking down billions of trees just to make paper seems increasingly irresponsible, and a gradual migration to eBooks is probably inevitable. I've had the Kindle app on my iPhone ever since it came out, and have downloaded and read dozens of books on it. Unfortunately, the shorter battery life of the 3GS compared to my original iPhone means I am using the iPhone less often as a book reader (especially on long flights), but I haven't given up on the concept just yet. So if you like reading books on your iPhone, what's the best way? As is, while I like Amazon and the Kindle app, Barnes & Noble remains a formidable force in the book market and so I decided to check out the Barnes & Noble eReader as well.
