According to BizJournals, Amazon has just acquired Mobipocket:
Franklin Electronic Publishers Inc. sold its shares in a French software company to Amazon.com Inc. and retired 29 percent of its outstanding preferred stock.
The Burlington City, N.J., publisher of electronic books sold its 16,765 ordinary shares in MobiPocket.com SA to Amazon (NASDAQ: AMZN) in connection with Amazon’s purchase of all MobiPocket’s outstanding shares.
I’ve read much more through eReader on my Palms, but I suppose those days are numbered with Amazon in the game.
