1981 Osborne 1 portable computer - GIF

I had an Osbourne like that. It was my introduction to home computing. IIRC I only used it for word processing with WordStar. I did a lot of writing at that time. A normal line length was 80 characters but the small screen could not handle that so it showed only part of a line, I think that is was 50 characters. So to read a document you had to scroll sideways back and forth to read a full line. That was really tedious and I replaced the Osbourne with a Tandy which was a huge improvement.
The Osbourne used the CP/M (or was it C/PM?) operating system but the Tandy had its own propriety DOS.
