Side-loading on the Kindle Fire is no harder than it is on your typical Android phone. A significant portion of Kindle Fire owners will side-load apps if someone gives them an incentive to.

Given that, I expect that side-loading on the Kindle Fire will be as insignificant as side-loading has been on Android phones. After all, it isn't like phone side-loading helped a company build an app store that they later married to their other content services to make a rich ecosystem for a new tablet, now is it?

Oh, wait...
