In the early-mid 80s the art of laptop computers was just getting started.
That's a picture of the TRS 80 Model 100.
It ran Microsoft software, if I remember correctly -- couldn't run what we now call "apps." But it had a little word processor and a BASIC interpreter, and could connect up to your desktop computer. I owned one, but never really used it. I was an Apple II guy at the time, about to transition to the IBM PC.
My first real laptop was the DG One. I was one of its early developers. Really made an impression. It was a real computer. Quite heavy, almost in what was then called the luggable category. The great thing about it was that it was not an almost-clone of the IBM PC, it was an exact clone. That meant it had lots of software. The near-compatible computers of the day all withered on the vine.
