In a publishing discussion forum I participate in, a friend recently posted her concerns over a recent announcement regarding exclusive content for the Amazon Kindle:
An article in today's New York Times announced that the Atlantic will sell some short stories exclusively on Kindle… This concept bothers me for a couple of reasons. First, the Kindle seems to be the most restrictive of the e-readers… Second, selling a short story exclusively to the Kindle is essentially creating a work that only a privileged few can ever read.
She's right that the Kindle is more restrictive than other readers, but not by much. The only advantage Sony's e-reader has over it in format compatibility is in its support of ePub files, for example. Wikipedia has a handy chart that compares all the hardware's compatibilities.
As for why anyone would choose to make their content available on only the Kindle, check out this table of who owns the e-book market: a quarter of all e-book readers are Amazon Kindles. That's twenty-five times greater than the Sony eBook Reader, and many more times still than the unproven nook. If the Atlantic wants maximum exposure for their content, it makes sense to go with the market leader. (And it's possible Amazon offered them some strong incentives to provide this exclusive content — something e-publishing fledgling B&N couldn't afford while investing in launching their own product.)
However, though there's something to be said for getting in on the ground floor, I think it's too early to be pledging allegiances just yet. It was just last year that early adopters of the HD-DVD format found themselves orphaned in the face of Blu Ray's victory, as this comic strip recently reminded me, for example. How many of today's e-readers will soon be similarly unsupported? The Atlantic may see the potential in taking a risk with a particular product, but I'm more than happy to wait this one out, and then through my weight behind a sure thing.
If e-books were a technology that needed my support to survive — so many people skipped the Sega Dreamcast in favor of its eventual successor that there was never the sales to warrant a successor — then I would be less hesitant. But given the nook's overwhelming presales, I don't think electronic publishing's pioneers will suffer for my economical patience.
