Listen, get them docking stations, set their lovely built in screens down to the lowest supported resolution and get them 19" 1280x1024 flat screens (~$700, I got one for my 88 year old grandma - yeah she uses a PC regularly - she's too cool) and a copy of Pivot Pro so they can put them in portrait mode for reading the WSJ or NYT. That way they only need to look at the built in screens when on the road.

If they're not too old, or still brand new(the machines that is, not the businessmen) Dell might help you out by installing the lower res screens instead, so long as you asked nicely and didn't ask for any money back.
