I'm a little torn between going for a cellular iPad air or the wifi only one. It would be nice to have cellular capabilities on the iPad, especially with the shift to "shared" data plans. Also with AT&T's new data plans for the iPad. Namely the 1GB for 3 months. It's tempting to get the cellular one. Oh yeah, there's also the GPS chip in the cellular iPad air that the wifi only one lacks. But not sure if all that justifies the 130+ greater price tag. I do have tethering on my phone, which I can use on the wifi iPad when need be. And I do plan on using it mainly in wifi hotspot areas. Such as home, work and coffee shops etc.
