Went to Best Buy to get an iPad Mini 4 128GB Cellular and was told they are no longer available. Only options in cellular are 32 or 64GB from cellular company at $600. Would they be good for a MPP? Can WiFi version be okay even without GPS. I think only changing RTH on the fly and Follow Me will not work with WiFi model. What other tablets are people using? I would consider something other than an iPad Mini 4.
