More control.

iOS is still a Procrustean bed. At least, with Mac, MacBook laptop, etc., you still have access to open source things.

Also note that the real productive people, the people who program and build things, still use a laptop.

My thought on the future: the poor and unproductive people are just addicted to the iPhones, whereas the real producers and productive people all use a laptop to actually build meaningful things.
