I'm wondering what would happen if people could pick between different app stores for their phone, much like how a Linux system allows you to get packages from multiple repositories. Benefits to third parties: They could host their own "app store" and monetize however they like Benefits to developers: They could put their products in any store that will take them, or perhaps try for Apple's "high quality" store for potentially(?) higher gains. Benefits to Apple: They could police all they want and people's claims of "Too much policing!" would be groundless since consumers can just switch stores, though it may be harder to monetize Is this how Android works with Amazon's "app store" competing with the Android marketplace? How is that working out?
