&#62;Are tightly closed environments like this where we want personal computing to go next?<p>I think all signs to point to yes (assuming you use "we" to mean the population at large and not HN). Outside the mobile world, look at the example provided by consoles. They epitomize the idea of a locked down environment. Look at how popular they are compared to PC gaming. I think that consumers want the slick, easy to use, "it just works" environment much more than they want an open environment.<p>People don't like it when they have to sort through the web to find software of marginal quality. With a closed system a gatekeeper filters this out for them.<p>I think there will always be a market for those who want an open system, but it will take a back seat to closed systems. It'll be interesting to see how this can be implemented in practice. The idea of a "root mode" for advanced users and "simple mode" for regular users seems like one possible solution.
