This is what infuriates me so much about the new Mac portables...they clearly were designed by hunt-and-peck peons. Software "keys" that you have to look down to reliably hit, word suggestions (implying you should looking down at the keyboard instead of the screen, which is flat out wrong...) and scrolling emoji. Never mind the key failures...

I'm surprised you say this. I have no problem touch typing with one, or two thumbs on almost any phone displaying a qwerty keyboard after orienting myself to it.

I'm wondering if you have very specific muscle memory outputs for your fingers vs. an intuition of where each key is relative to each other. E.g., I'm typing this sentence with only my pointer and middle finger on my right hand. Would that cause a problem for you?
