Picking which operating system to use enhances lock in by itself already. I've bought software both inside and outside of the mac app store and since I have that software I'm locked in to the program. If I could move all my applications to the app store I would do it in a heartbeat because it gives me one place to go for updates. Apple is certainly missing out on opportunities, but not only for "locking people in" but also for making their user experience better.
