I am also using my laptop, with Earthmate GPS and Delorme Street Atlas. I love the larger view.
I am thinking of going to PC Miler for Trucker specific routing, and Sprint is offering it through the broadband card, so I can continue using my laptop. I will check into this more when I get home.
I thought about the little dash units...but I have become spoiled.
Anyway...the Sprint's PC Miler for Truckers...is offered on the cell phone too. That seems handy...if you are also willing to put up with smaller screening.
You can have it all on your phone now days!
If you get in a crash...you can even watch yourself on the News with TV viewing on your phone too. :lol:
Someday...I hope all this crap can be on a tiny chip they just implant in your brain. 8)
