To do away with the walled garden approach would require a robust, scalable solution to the malware and spamware problem. For most non-pro users, a walled garden is awesome. You can actually use a computer without it becoming progressively more and more infested with malware and without it "rotting" from badly written installers, etc. For most users closed is a feature, not a bug. Closed means it works. Closed means you don't have to do your own IT. A real solution to these problems that isn't based around walled gardens and app whitelisting would require very innovative solutions to major problems in application and operating system security. These aren't the kinds of problems that get solved overnight, and unfortunately I don't see very many people working on it. Ultimately I think what's going to happen is more pragmatic: the computer market will fully bifurcate into one kind of device and OS for power users and developers and another for everyone else.
