Andrew Sullivan, in "Reviewing the Kindle" at The Daily Dish at TheAtlantic.com forwards an idea, as a fan of small, fast, compact printers:
What I'd buy is a small printing device that can download any book and print it out in a classic simple paperback style: a consumer-friendly print-on-demand.
Rob Enderle, in "The Rise of ePaper: Could Kindle Represent the End of Printing?" on his blog at ITBusinessEdge.com, beyond some good commentary on the Kindle itself, offers the idea that this could be the beginning of the end for printing. He asserts interesting arguments about our (printer) industry that speak to its mature status, seeing low (single digit) sales growth but high profits at least for the dominant player, HP (NYSE: HPQ).
In short, this has the feel of a business that has peaked and is in the process of being replaced by something else.
