Yup, this kind of stuff is very much based on preference. I think some people have tighter comfort deadbands and others are tolerant of anything. These can be the same person, on different days / differing amounts of sleep / different tasks / different lunches / different music. i.e. I have a three monitor setup, two 1080 screens and a central 1440p screen. Mechanical cherry blue keyboard and a nice gaming mouse. Big desk. One of those anti-RSI boob mousemats. Nice headphones. Beefy computer. Ergonomic office chair. Everything at the right height. Quiet room. Next to an open window, but which is in shade. Some days I will happily chug away writing reams of code. Other days I will get nothing done and every minor annoyance will bring me out of focus; background sounds, glitches in my desktop environment, almost inconceivable hitches in computer performance, my chair feels wrong, the contrast of all text is too high, it's too dark in here, it's too bright, this is all bullshit, I'm so done with computers... And on other days I'll get even more done, hunched like a Goblin in my living room armchair with my legs tucked beneath me, working through to the early morning, on my tiny 13 inch dell laptop, vaguely aware that I have searing pain* through one wrist, having not eaten for 12 hours, but completely and utterly content and in flow writing code or a paper. Humans are crazy fickle. There's no Platonic Ideals when it comes to Crushing It(tm) as a software developer. I think learning the art of mindfulness and meditation does more to help you focus than expensive equipment fads and micro-optimizing your environment. * Before anyone mentions, yeah I'm aware RSI is Not Good. I've got a bunch of various remedies for it. Ironically I've found that bouldering helps with this it the most. Just not able to do that during lockdown :(
