Neat! I read something a while back that suggested the same result and my experience seems to conform; a keyboard sitting nearly in my lap with a slight negative angle is most comfortable for me.
As my keyboards sit a little higher than they ergonomically “should” (elbows at 75/80 degrees rather than 90), flat seems comfiest for now. I know I’m in the minority.
When will keyboard trays be cool again? (and compatible with low mouse sensitivity gaming?)
Edit: whoa this is kinda old haha
