(CNN) -- I have had laptop computers since 1985 and as they have become more powerful they have freed me from the constraints of location.
I have two homes and an office, and travel to give lectures almost every week.
Yet with my laptop computer and periodic Internet refuelings, I can continue to work the whole time as if I was chained to a desk.
I open my laptop in the taxi and close it only during takeoff and landing.
I write books and papers, prepare lectures, do administrative tasks, and keep up with correspondence, so my students and colleagues don't even know I'm gone.
When I want to relax I have my entire music collection with me, or can indulge in my hobby, photography, by doing digital darkroom work.
Then when I get home I resume my real life immediately, as if I had ever been away.
Without a laptop freeing me to travel, I would not see nearly as many places, meet nearly as many people, or be exposed to nearly as many new ideas.
