Every time I buy new iPad I want to try cellular version and every time I go with wifi only due to price difference for the thing I will have never been using and requirement to buy extra mobile plan for this. I have Wi-Fi available at home, office, airport, cafe or via my iPhone. if I need more energy for iPhone I will buy powerbank (wasn’t required since my first iPad purchase in 2013) and it will be still cheaper than pay extra bucks for cellular version in my location. Everybody has own workflow, but nowadays I think Wi-Fi only version is suitable option for most people.
