For the last two years I have had a Dell Optima with me as I drive around from Kuranda to Croydon, Chillagoe to butchers Creek. Often the roads kick up huge amounts of dust and can be rough in some stretches.
The notebook sits in a backpack lying in the back of the Nissan X-Trail. It has never missed a beat.
I am not saying rush out and buy a Dell (although we have found them to be reliable) but in my experience an ordinary notebook is fine. It has been bounced around a lot, but being in the backpack inside the car it has not had dust ingress.
On the other hand, you can kill a hard drive at any stage of a computers life so all the advice on backing up, etc is valid whatever choice you make.
