I was thinking of possibly springing for the full LTE iPad pro when it is released. I've only owned WiFi iPads in the past. I have a few questions for the past iPad LTE versions vs Wifi Versions: Is the upload download speed faster on the LTE vs tethering from 6s Plus? Is the battery effected on the LTE version vs the Wifi Version. Will the wifi version last longer? Does the LTE version use more Data vs tethering?
