The standard staggered keyboard layout not symmetrical. If the layout of the keys were optimal for the left hand for instance, the "u" key should have been slightly to the right of the "j" key in order to have the same experience with the right hand. A good way to see if a keyboard actually tries to be ergonomic is to see if the left and right hand layouts are relatively symmetrical.

This argument is insufficient - even taking it at face value, it's only an argument that an optimal layout will be symmetrical, not that a given symmetrical layout is necessarily superior to a given asymmetrical one. In the context of straight columns, what seems strange about it is that my wrists are naturally at an angle when typing, because the width of my keyboard is less than the width of my shoulders. Straight columns intuitively seem like they would require more wrist distortion, not less. This might not be the case on a wider keyboard, but I don't think typematrix ones are significantly wider than 'normal' keyboards? I don't know if this reasoning is accurate or not, and I'm sure it can't be a real issue because typematrix keyboards are clearly popular, but I'm not convinced about it just because they're more symmetrical. Plus, in terms of general typing efficiency, I also don't know if I should believe the symmetry is actually important - it might be negligible compared to (for instance) the inefficiencies of qwerty that most people are using, or even compared to simple posture improvements.

  Yes, I'm not saying the TypeMatrix pure grid layout is 100 % ideal, maybe there should be just a little bit of stagger to account for the angle of the wrists - but there should still be symmetry of course. I think the TypeMatrix is far superior to the standard staggered layout though, when it comes to the concerns you raise. The standard layout is just horrible, reaching "v" and "b" with the left index finger while keeping the rest in home position requires an uncomfortable amount of stretching. Even for the right hand, I think the standard layout errs on the side of too much stagger, which is evident when using the pinky to hit the "/" key. There is certainly a lot more wrist distortion than when using the TypeMatrix - there tends to be less distance between the "a" and "l" keys on a standard keyboard as the TypeMatrix places the Enter and Backspace keys in the middle. I guess the Kinesis Advantage might be more ideal in that regard, though I don't suffer from any significant wrist distortion with the TypeMatrix. My hands tend to look like this when using it: https://ploum.net/images/tmhands.jpg https://ploum.net/images/tmhands.jpg The small size of the TypeMatrix also makes it a win for me, as I occasionally bring it along with the laptop when I sit in the couch for example. Qwerty is another inefficiency, and I use Colemak myself. The difference between a standard keyboard and the TypeMatrix is still far from negligible.

    Well, this is interesting to hear, thanks for explaining. I also use colemak, but I've been leaning towards using a wide layout (swapping some punctuation from the normal position to the centre of the keyboard) - it's from this perspective that the typematrix looks unappealing, but I'm happy to believe this is just a misleading intuition. I do like the typematrix movement of enter, backspace etc. a lot, that part is undeniably an improvement.
