I got a job driving a truck long haul, in a week I will have a truck all to myself to outfit how I like. I found a stand that will work for my 17" MBP and let me use it from the driver seat. I would love to use it for navigation. Is there a navigation/GPS solution that does not require an Internet connection? If not OS X native than something that will work well with Parrallels/VMWare. It MUST be easy to operate. Would it be worth it to upgrade to a solid state HDD? The roads are quite bumpy, even moreso in a big truck, and I'm concerned the the sudden motion sensor isn't quite enough protection from the bumps. Any other recomendations for a laptop that will be on the road 25 days a month.
