Kindle in danger of becoming ebooks’ Betamax

Amazon’s competitors, after fumbling about like the Washington Nationals for the past couple of years, are starting to get their act together. They’re moving toward a shared e-book format, called ePub, that’s different from the one on the Kindle.

And Allen Weiner, an expert in the e-book business at technology consultancy Gartner, Inc., says he knows that other manufacturers are poised to launch new reading devices with Kindle-style 3G wireless connections. Some may be announced as early as the next few weeks, he says.
