Reflective active matrix LCD screen (fast response, no ghosting), full-travel mechanical keyboard, movable trackpad, built-in floppy and hard drives, expansion slots, all-day battery life. And an attractive and clever industrial design (note the cutouts for left-handed or right-handed trackball placement.)
Fantastic design for someone who didn't mind a bulky, 16-pound "portable". ;-)
In 2024, portable Macs are better in nearly every way (including battery life) but the keyboards aren't nearly as nice, and the screens aren't great in broad daylight (unlike a reflective LCD.)
(And didn't Apple subsequently invent the "palm rest" laptop design where you move the keyboard back toward the screen?[2])

I have a Portable in the attic somewhere, and I used to boot it up and play around with it a bit. The screen was dark (no backlight) but very crisp and relatively smooth for the era.
Its carry bag had only a shoulder strap. It should have had a full-blown backpack to distribute the weight better.
