With the ability to tether my Iphone 4 to an Ipad 2 (upcoming 4.3 IOS release pending) do I need to opt for the 3G ipad or save the money and stick with the Wifi only model. As an FYI I had a 64 GB wifi+3g Ipad 1 and just sold it to help fund my Ipad 2. I did enjoy the 3G but there were times where I wouldn't use the 3G data for weeks since I was always able to get a WIFI signal. Curious your thoughts and welcome the feedback. I know this is user dependent so I am curious why folks will opt for one over another.
