I'm not sure I understand what you mean by environment. Could you explain? The reason I ask is that I don't think I'm lock into anything with my iPad mini, why do you think I'm locked into?
Again ? Are you really saying that the Apple environment isnt more locked down
than Android ?
Try buying an app from a store that isnt itunes .......
Try changing the default mapping app to Google maps....
The Apple ecosytem is more controlled and insular than Android.
Whether thats a bad thing or not is a matter of perspective.
