I use Colemak DH for many years and Dvorak before that and I am of an opinion that alternative layouts are way overrated. I even somewhat regret inventing so much time in learning them. QWERTY is just fine!

The matter I want to preach about tho are split ortolinear keyboards. I believe absolutely every typist should use them. Conventional keyboards are just bad from ergonomics perspective and eventually it’d have a toll on your wrists health. And many of these keyboards stores key mappings directly on the chip so no need to mess with weird mapping software.

Having said that, my split keyboard is one of the best investments I did in my life.
