I own a small fleet of OTR trucks and drive one of them. When I leave the house I'm gone for several weeks and then I go home for a few weeks. I'm debating whether to go with a MacBook or a 20" iMac. My wife works for the school district so I have access to the education pricing for whatever I choose. I know there are carry cases made for the iMac and since it would only move from home to truck or vice versa about 10-12 times per year the bulk and weight shouldn't be a problem. I'm not sure about standing up to the dust and vibration riding around in the truck though. Another option would be to use the Mini and plug into the 15" flat panel the truck has for dvd's etc.. Any and all thoughts and comments are appreciated.
