MY ACTUAL QUESTION: Other than the built in GPS in the iPad, do you give up anything by going iPhone+Tether+Wi-Fi iPad vs. 3G iPad? RANDOM MUSING: If you own an iPhone, you can tether the phone to a wi-fi iPad. Or, you can get a 3G iPad. Cheaper to tether, but it drains the more limited battery of the iPhone. But you can also tether it to other devices. Is there a consensus on the forums as to which method is more popular? I'm personally leaning towards a 3G iPad 3 to replace my wifi iPad 1. I don't have much else to tether to, but it would be nice when I need it.
