In today’s lead story, author and book marketer M.J. Rose writes that her company AuthorBuzz.com, recently conducted a poll with 200 people who own e-reading devices.

“Every one of them reported they were buying at least two times more books because of their e-purchases. Some reported a 300% increase,” she said.

Granted, this is a small sample, but the numbers are impressive. I can verify that since buying an Amazon Kindle on the first day it was released, I have certainly bought far more books that I might otherwise: I’m trying, first and foremost, to justify the several hundred dollars I invested in the initial purchase of the device and to make use of it.

But I can’t say that I’d buy any more titles than I would normally if it weren’t so convenient to simply click and have the book appear a few minutes later. There’s a lot to be said for instant gratification, and frankly, not being able to cancel or return the purchase. Typically, when I shop in a bookstore I walk around gathering books in my arms and return several to the shelves before making my final purchase.

I also own a Sony Reader, which I have never used, having found it just too difficult sync to my computer, register a credit card, make a purchase and hope it all works.

So, tell us, what is your experience buying books on e-readers? Do you buy more than you otherwise would? If so, what is your reasoning? Do you simply enjoy reading e-books on the device or is it something else?
