Everybody wants to stay in touch while on the road just as much as at home and we are no different. From email checking, to menu research and planning, as well as looking for that next campground, making business plans, and even social networking or maintaining this blog. My wife and I both use IPhone 5s, but still wanted a laptop for our RV as a way to not only communicate, but to research, plan, and print.
Of course the Jetpack is only as good as your cell phone signal strength as that is exactly what it is; another phone line. Tethering our IPhones with the laptop costs $15/month and the Jetpack can supply WiFi to several systems for $20/month. In the future I see myself investing in a directional WiFi antenna and possibly even a WiFi amplifier for those fringe areas. Nothing, of course, beats logging on to report our travels, upload photos, or share menus at the nearest McDonalds or other free hot spot.
In the end though, being 'off the grid' means exactly that and as such we want to have the choice and power to communicate when and where we choose. Joie de Vivre!
