"the nook accounted for 53% of e-book readers shipped to US vendors"
I suppose Amazon's primary business is not shipping e-book readers to vendors. Without more information (% of kindles shipped to vendors as opposed to direct sales), the numbers are pretty useless.
We have now updated fifobooks - the entire catalog is browsable on the web, and you can buy and download books (epub, mobi, or mobi dx). Because you download the ebook file, you can put it on any ebook device imaginable, including mobile phones such as Blackberry and iPhone.
