I have the 32g wifi+ 3g. I have not used the 3g. I got a great deal on an unlimited usage mifi thru Verison, so I use that, since I can connect up to 5 devices. So when we travel everyone can connect. I think the 3g should add to the resale value if I decide to sell it at some point. I just like the option of know I have it if I ever need it. My husband had a 3g too, and loves using it when he is traveling and out and about.
I see your point, but the wifi in a lot of places I've been doesn't work very well for some reason on my device, usually kind of slow.
