This is another reason why I believe rooting/sideloading won't be as easy as people are assuming. In fact, it most likely will not be possible.
Amazon has rigid control over this device. It's not entirely their fault, but they have to in order to ensure it pays for itself. And to present an environment that appears to be as stable and secure as Apple's iOS.
The Fire is paid for by ads and end-user datamining. No, it is not $200 because they put cheap parts in it. Quite the contrary. They will not allow people to install their own OS, and potentially work around Amazon's only way of profiting from this tablet.
