What, an article on typing and keyboards, and no mention of Dvorak or Colemak? Let's have that eternal discussion again! Swap Caps and Ctrl, use Emacs or vi keybindings, and save your wrist from moving to the arrow keys!
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.
