I'm thinking of buying my first iPad but haven't decided if it will be a discounted iPad2 or the new one. I was pretty set on just getting a WIFI only version. Are there many popular apps that users are using that require an internet connection that makes buying a 3g version a must. I have an android phone and I notice that even many games need that data connection just to upload high scores or use openfeint. So if I buy a WIFI only model will I be limiting myself too much as to which apps I can run?
