Similarly Apple can choose what standard interfaces and protocols to implement and which proprietary ones they would like to create. > why does it change when you add a cell radio? Because that's what Apple chose to build and sell. You're free to build your own phone with your own feature set and sell that. > Don't fall for Apple's marketing Fortunately I'm capable of my own rational thought. |
