"production" ones, at prices only business could afford.
While working for KPMG I had one of the first Apple Powerbooks nearly 20 days ago. In those days, only 'corporates' could purchase them.
I think Ive had 9 PC's and 6 laptops (both including 2 macs) in approx 25 years.
I had 8 years service from one laptop I only just replaced.
