hmmm, a tablet in my truck..... no thanks. and using my phone to run my truck? no thanks. I can just see it now.... driving along and my phone decides it's gonna shut off (it has happened), and then what happens... does it keep the files and just keep doing its thing or does the truck go tits up and you're stranded til your phone decides to work....

I think I'd rather stay with something that is mounted in the truck and never worry about it.
