If I can make a suggestion...
If your going to buy an iPad buy one that has 4G Support. Even if you never activate the 4G service you will be happy.
My first iPad was just a WIFI model, and it didn't get much use since a majority of the apps required an internet connection. If your at home its one thing, but outside of the home it was useless.
My next iPad I got it with internet service... once I did that the iPad became part of me and I carried it with me everywhere. Now when I go out it is rare I bring my laptop with me, as the iPad can do almost everything. I can check my mail, in case of server issues I can access the servers, watch my home security cameras, watch live TV via my Hoppers... etc.
As I said get one with 4G but don't activate the service.. and use it and soon you will feel you need to turn on the 4G and you will be glad you have the ability to turn it on without having to buy a new iPad.
