David, I do not have a laptop, but on my experiences on United and COntinental in
business and first class I have not seen any
problems my fellow travelers have experienced. In fact, this holds true in Coach.

The flight staff generally does not mind the
machinery as long as they are turned off and
turned on. IT's become so common to me no
one seemed phased to see a laptop on board.

This is a good article and when you are done
I'd like a copy (to help me when I have to
use one in the air.)

GOOD LUCK! CATMAN
