From 1993 to 1994, I owned a PowerBook Duo 210 sporting a trackball, a low-profile keyboard and a grayscale screen. I didn’t like the trackball as the pointing device. The keyboard wasn’t that great either. But, it was small, highly portable. Coupled with the Duo Dock and an external monitor, it was a cool and novel setup. It’s been a long time ago. This article was written using a M1 MacBook Air, in a coffee shop.
