I've read one comment on here about this topic "make my truck a hotspot". With all the technology we have today, will it be that difficult? Create a partnership with one of the big wigs in wireless like AT&T, Verizon, or Sprint. Would make long road trips a bit more bearable. Most of us have smart phones nowadays but it would be a great thing for kids. My five year old has a NABI tablet that she watches Cartoon Network or Disney or what have you while at home but when we no longer have an internet connection she loses that.

I have a hotspot and have used it on the road. The issues are losing signal strength while traveling and the providers are starting to charge for the data used.

My vote is to use a Hot spot but allow it to be charged via a USB. Just a thought.
