Honestly, if you are already running with other Mac products it really only makes sense to go with the iPhone. The real upside to Apple is that everything works seamlessly with all other products, and tossing an Android in the mix just complicates things.

I'm sure many Mac users are going to argue with that statement, but it's kind of pointless to get a different phone when you are already set up with Apple.
