Yeah I think that dvorak is a good example, too.

I don't get the mechanical keyboard one, though. I am fine with any keyboard, I just like my mechanical keyboard at home. Just like I am fine with any chair, but ideally I would have a chair I like at home.

120fps I have no experience with, but I would imagine it's closer to video quality. Once you're used to watching everything in 4K, probably it feels frustrating to watch a 1080p video. But when 4K did not exist, it was not a need. I actively try to not get used to 4K because I don't want to "create the need" for it :-).
