I have. to say that the keyboard on the M3 Air is good but far from great. I was expecting a keyboard that would be as good as the Magic Bluetooth keyboard but it's clearly a step down. The keys are inconsistent for feel when pressed. Why do the outside keys like tab, shift, enter have key wobble? You press the outside of the key and it feels looser than when you press the middle or inner part of the key. I could overlook it if it was just one key but this applies for the delete key, return, shift, caps lock and tab. That to me is unacceptable. For the money you pay, the keyboards should be flawless.
Maybe I'm just spoiled with using mechanical keyboards and MX Keys over the years but even the type covers on the Surface Pros is far better for feel and typing experience.
