Anyone here using a split ergo keyboard such as the Iris or Ergodox for example? I've been looking into them recently due to my noticing occasional aches, pains, and strains in my wrists and shoulders. Just wondering if anyone who has made the switch from a regular keeb to an ergo could offer some feedback? Was there much of a learning curve? Have you noticed the benefits? Any disadvantages? Good for gaming? Thanks in advance!
