great, all these keyboards have a control key, specifically, where a caps lock would be today. it's been around for a while, that's a nice fact. how many of these systems can run windows and these OS agnostic apps you speak of? man, i'd have a hell of a time switching to any of those. how many windows systems have the control key in a different location from where it is today? how does that negate any physical distance between two OSs and my struggle switching back and forth between the two? it's muscle memory. it's like trying to draw or write with your non-dominant hand.
the objection is that the ctrl key on mac performs a different operation. ctrl on windows = cmd key on mac. you would know that if you read the article you linked before replying with a sigh (see "similar concepts") or even used keyboard shortcuts.
you guys are acting like keyboard shortcuts are a non-issue between OSs, and maybe for you or probably even most they aren't, but for myself (and probably a few others) and the work i do, i need them to maintain efficiency. as stated earlier, i've even gone as far as remapping on the windows side to be more like the mac side (where my muscle memory resides) but even then there are still variations on shortcuts in apps like photoshop and illustrator. can you understand that there is a difference between the two or should we keep moving the posts back to the 70s and typewriters?
