Re: I'd try Linux mobile
In my somewhat unique profession, I do route surveys for oversized loads. Which means my contracted employer gives me dimensions of an object that needs to be transported over public thoroughfares, from here to there, and it's my job to determine how to get it there.
I still use an LG Nexus 4, from what, two years ago? I can print maps, routes, location pics, Google Earth, and anything else I want or need from this phone, in 99% + of anywhere in this country.
OS management/understanding is paramount with any flavor of any modern device.
