A few of you asked why someone would want a hotspot in their car - when my company phone did have the ability to provide wifi, I would often find myself needing to fire off an e-mail with an attachment, which couldn't be done with either my iPhone or iPad - it needed to be done with my laptop. And because I drive quite a bit and often find myself out of proximity to a Starbucks/McDs/Panera, the hotspot really came in handy. My company has since done away from the hotspot on our phone option.....something about reducing non-critical expenditures????
Another instance where a hotspot in the car might be handy came up yesterday when my wife and I had an 8 hour drive to make and she really could have spent that entire time doing work while I drove.
It's definitely not a necessity, just a nice to have - I think more and more cars will offer this feature in the near future. Per my earlier post, the Jeep GC I'm considering (as well as most of the Chrysler line up have this as a subscription feature)
