Up until this iPad Pro, I had wi-fi only ipads. For the 9.7 iPad Pro, I decided to go with the cellular model. The reasons being are: I'm in ministry and I get asked to guest speak/preach for retreats and conferences and a lot of those are away from a good cellular connection w/LTE (especially for AT&T). So having the cellular iPad allows me to purchase pre-paid data through Sprint or Verizon (whoever has a better coverage map for the area).
