Openness is not a concern for the people who buy Apple devices, and probably not for the public at large. It certainly is no concern to me, I need a machine which works so I can get stuff done. For a MacBook that means opening the lid. For a Windows laptop that means plugging it in, opening the lid, waiting for half an hour for the system to update while it is unusable and hogging all the bandwidth at this time, etc.
Smart phones took over from personal computers, because people want something which works and they hate having to fiddle with their device, trouble shoot and fix things. They don't care that they can't install an Arch Linux terminal on it or download torrents. And if they need something more pro, they go for an iPad or a Macbook when they can choose. Openness is only important for programmers and people who love to mess with their device, not for the public at large.
