I read on my commute to/from work. Not sure about the # of books I finish a month, but I can say that I may be willing to "experiment" more with books I wouldn't have otherwise. No downside to read the first 3 chapters and then switch to another book, if you don't like it. I think, therefore, that it might be a nice DISCOVERY tool.
good point. The only issue with Amazon that I found was that the first sample chapter might be 5 pages long, so you don't really get a flavor of the book. I might be wrong though (maybe they now do it by total length rather than chapters)
