This is a great list to start with! I made the decisions/mistake to purchase a wi-fi only iPad early last year. I love the iPad but have often times regretted not bucking up for the 3G/LTE version. I tried tethering to my iPhone, and although it is a good solution if you are really in a pinch, I would remind anyone doing this that it could potentially rack up your data overages as it did to me. Thanks for the great list and I can’t wait to try out the hot spot sage!
