Early adopters of Apple's iPad have poured their money into 5 million digital books within just a couple months, fast-tracking the device to a 22% e-book market share.
That announcement came at the Apple World Wide Developer's Conference today. Although the electronics company is usually gunshy about announcing specific sales numbers, it was all about boasting them today.
Steve Jobs said that 35 million iPad app downloads have been logged since the device went on sale in April. That's about 17 apps per iPad, on average, though Jobs didn't elaborate as to how many of those were paid apps and how many were free downloads.
The e-book news is undoubtedly frightening for Amazon, which had enjoyed a near monopolistic stake in the e-reader market for years after it originally released the Kindle.
Amazon is coming out with a new version of its device, but will stray away from some of the more mainstream features of the iPad, like a full-color LCD screen, unrestricted Web browsing, and extra apps.
