I bought the Logitech ERGO K860 and just couldn't get used to where the B and Y keys were located. Over a decade ago, I was taught to use my right index for B and left for Y. Apparently that's wrong, but it's too late for me to unlearn that typing habit. I gave it away and bought a standard single continuous board keyboard instead.
Comments on Split keyboards give your hands a break but reduce typing flexibility
I've always been curious about split keyboards. They seem gimmicky and I hadn't fully considered that they limit how I type. The Dygma keyboard looks really cool though!!
