We have the WiFi only Ipad2. It was a gift for my 4.5 yr old from her grandparents. It is amazing. I'm not exaggerating when i say we took out the box, i downloaded itunes and handed it to her. It is very user friendly, which you may like. I do not use it as much, it is mainly a gaming pad that we take on trips, restaurants, doctor appt, etc. Anywhere that there is a wait and she may need to be entertained. But there are so many features im sure you will use. We did get the 64gb because we wanted to have as much space on there to download her fav movies(handy when we are on a plane in 2 wks). I knew i would never pay extra for wifi anywhere but get it if you already know you may get a plan in the future. Our sales guy was pretty honest about how "anywhere" is not exactly that and they are still working on the kinks. Most restaurants, airports, kids places, etc offer free wifi anyway.
I have heard good things about the HP touchpad that is limited right now. And also the Kindle Fire. But having an Ipad i can tell you im very happy and will never buy anything else :)
