I’m still getting used to the Model 01, so take this with a small grain of salt, but I find myself wanting two changes to the keycap shapes in what is otherwise an excellent design.
One is that I think the single/double quote and PageUp keys need to be just a little taller, maybe 1mm or so. As they are, I feel a little like I’m sticking my pinky down into a hole, and sometimes I also accidentally press the minus key when going for quote.
The other is that I think it needs to be easier to tell where my thumb is on the thumb row. The little bump on Space and Bksp is helpful, but sometimes it takes me longer to find it than I would like. I think those keys should have a very different shape from the other three, even maybe concave on top with distinct shoulders. Not only would this make it more obvious when my thumb was directly on top of the key, but where currently the three positions halfway between two keys all feel the same, with this change they would all feel quite different, so I would never have to move my thumb more than half a key to know where it was.
What do others think?
