From a cost per function the Ipad is about 300% overpriced a good Chines 10.1 screen beats the Apple 9.7 which is not optimised for video. Android will give you far more with external GPS and you could afford to buy 2 for back up and spend less than Apple with less performance. My 10.1 inch has 10 point touch screen has micro usb, HDMI, microSD, Bluetooth, WiFi , quad core and big memory built in , it will support more video standards plus front and rear cameras. The Apple is designed just to make money from the less technical adept and is very restrictive from what you can do with it. My wife has an AIR11 which is most frustrating at times if you try and step out side the box Apple has limited you to but inside that box it does it well.
So for the cost of a Chines Android plus a 2 channel GPS it would be half the price plus there are lots of apps. So compare before charging down the Apple route and they run Sky Demon OK.
