The Cellular model gets a dedicated GPS chip.

But other than that, and if you plan to tether. the 32GB Wifi only version is a better choice.

You need cellular if you want GPS on your iPad, so you can get directions as your traveling. I don't know if tethering will accomplish that.

When tethered to the iPhone the iPad will use the iPhone's GPS location as a basis. So yiou don't really need the GPS chip on the iPad.

Aloha Phil0124, I knew someone would know for sure. Thank you. Bob.

You could drop your iPhone plan and go VOIP on the iPad Mini (cellular)..

  Works well if you are not a heavy telephone user..
