I prototyped something very similar during covid using a 3d printer, a blackberry keyboard, and a teensy. I don't think this is going to generate many long term users, even though I was enthusiastic enough to hack on it for a bit. * So much of my typing includes selecting emoji, using odd symbols, and the need for inputs not provided on this. In addition, having to switch between the touch screen and keyboard as inputs was very annoying. * It significantly decreases the experience of using the phone in touch situations. * I was using it with my iPhone mini and the phone and case had terrible weight balance. My hands fatigued quickly. I can't imagine how bad it would be for a iPhone Max. * I lost the use of my port.
