Butterfly style mechanism on an optical switch? I don't see that working too well. Optical honestly requires repeatable linear movement, and anyone who has ever used a laptop knows that the keys can be pretty wobbly. Every key switch mechanism has some wobble and movement to it, but from my experience, butterfly mechanisms are by far the worst, due to tolerances being fairly shit on them. With a switch mech that thin, I could see accidental registration being an issue. I also see issue in a few years when that keyboard gets gunked up with dust and hair; again, anyone who has ever used butterfly mechanisms know that they're damn near impossible to remove without breaking the tiny plastic pieces, especially after the product has gone through a decent amount of heat cycles. Magnetic switches probably would've been better in the use of a laptop, honestly. <br>I'm also curious what the affect on battery life will be.
