It is a little hard to determine which was the first portable or
laptop computer since the earliest portable computers to arrive did not
look anything like the book-sized folding laptops that we are familiar
with today. However, they were both portable and can sit on a person's
lap and did eventually lead to the development of notebook style
laptops.
With that in mind, I have outlined several potential firsts below and how each might qualify for the honor. Many of the off-site links provided below include excellent photos of the computers so that you should be able to see the progression in design.
The First Laptop? Maybe
The Grid Compass was designed in 1979 by a Briton named William Moggridge for Grid Systems Corporation. It was one-fifth the weight of any model equivalent in performance and was used by NASA as part of the the space shuttle program in the early 1980's. As far as technical specs, it featured a 340K byte bubble memory lap-top computer system with a die-cast magnesium case and folding electroluminescent graphics display screen.
