Agree Fly4Business but with Apple you are paying a lot for their software that you don't need for running SD so why pay for it and in the market Android out sells Apple.
The one thing to consider if you want a cell phone data connection for submitting flight plans and an internet connection from the cockpit then the Android tablet as in a Samsung may come up to the cost of Apple. I am just suggesting a cheap full junction Chines unit may work just as well and the saving spent on flying.
