According to Molly Wood, the Kindle Fire is missing the following features, “There’s no camera, front or rear; the 8GB of onboard storage is half the amount of the base-model iPad; the Fire has no cellular options, no built-in GPS, and no Bluetooth, as the iPad does. The software options compared to the iPad are minimal, and the app library for Android still isn’t nearly as robust as the iOS app library.”
On the other hand, those are all things my phone does. So, I would feel bad at buying a much larger, more expensive device whose only advantages are redundant with another device I own and always carry around. Kindle Fire win.
