Mobileread members are not a very representative group. By definition we know and care more about the technology behind ebooks than the average person and things like DRM stripping and sideloading are not huge obstacles to us.
A typical Kindle/Kobo/Nook/Sony user is almost never going to buy books elsewhere than the built-in store. He is locked in, for all intents and purposes.
