Google launched its e-bookstore today. The 300,000 titles — about half as many as available for the Amazon Kindle, but probably way more than Apple's iBookstore — will work on iPads, iPhones, Android phones and Google's web-based reader.

Google today announced "Google Editions," another e-book service alongside Amazon's for Kindle and Apple's for iPad. Google doesn't know what gBooks will cost or how exactly you'll read them, but they'll definitely piss Steve Jobs off, so full steam ahead!
