I use my iPad at work with no WiFi and at school with WiFi, so the only time I need the 3G is at work and I tether to fix that problem.

I cant justify paying more for the 3G service when i will rarely use it. And if i desperately need the internet i have my iphone anyway.


I was worried about the Location based services with the WiFi only but its pretty accurate when tethered as well.

I also imagine the WiFi weighs less and consume less battery too :)
