Forbes is reporting that the iPhone has become the country's top eBook reader. The claim is based upon the number of downloads of Stanza [App Store link], an ebook reader for the iPhone and iPod touch (395,000 and counting), versus the number of projected US Kindle sales (380,000).
For those unfamiliar with Stanza, it's a free application that lets users download books over the air, as does the Kindle. All of Stanza's offerings are free works in the public domain, and flipping pages is a breeze with the touch screen.
Of course, it's silly to compare an iPhone to a Kindle. The screen is very tiny and I wouldn't want to read anything longer than an email message with it. However, many people will, some of whom do it just because they can. I can remember reading a Stephen King book on my old Palm ///e simply because I thought it was neat.
Still, combine the 395,000 downloads of Stanza with nearly 380,000 Kindles sold (plus the Sony eBook reader figures), and it seems that many people enjoy reading very tiny type.
