Kindle Fire doesn't match iPad2 head-on: Performance, storage, screen size and resolution, the availability of 3G connectivity, and price put that device in a different league. But how many people who might have saved and eventually splurged on an iPad will now opt for Kindle's $199 tablet experience? The killer ingredient here is Amazon's content. There may well be Android apps that don't work on Amazon's heavily customized version of the operating system. But as for video, audio, book, and periodical content, Amazon has a bigger and broader collection available than Barnes & Noble does with its Android-based Nook Color.
