Help With Super Rugged Laptop Purchase.


Ok, have a question that I hope you guys can help me with.

Im installing a PC as a diagnostic and concrete mixture control unit and need something very rugged as well as something that is going to last in the elements (hot/cold/moisture/concrete dust). I used to support Toshiba Tough Books but never really cared for them. Anyone else have any personal experience with Rugged notebooks that could steer me in a general direction? I've googled some but I'd like to hear about first hand experience, and money is not an issue.
