One of the key reasons I prefer ThinkPads is that the little TrackPoint ClitMouse is one of the only pointing methods I’d still be able to use if I was shrunken down to legoman size. Trackpads, mice, touch screens, styluses? No way, not if you’re tiny. But that little red joystick? I figure I could manage it.
And part of my brain has been asking the question of “how could I use this thing if I got shranked all tiny?” since 1989, when I saw Honey, I Shrunk The Kids.
