> I wish Apple had attacked this from a different perspective. Instead of fighting side loading, remove the reasons that drive a lot of the demand for side loading.

Couldn't have said it better. The only things I could see myself sideloading are indeed the Kindle app (I like being able to single-click buy books without having to switch to Safari), a full browser, and possibly some retro computer, calculator, and console emulators.

All of these are (or at least have been, before I switched) been possible on Android via official apps from the Play Store.
