I entirely agree. At $NEWJOB, I had a Linux laptop for a bit while a Mac was on backorder.

Not being able to cut/paste easily because every tool used the Control key for something different, especially in the terminal, was infuriating.

Having the command key handle these kinds of GUI-focused interactions, and Control for most of the terminal-centric and text manipulation (Ctrl-A/E for beginning/end of line, from Emacs) makes the system great to work with.

I didn't mind anything else about my foray into Linux as a desktop OS. If we could get a Linux GUI distro that all it did was match the Mac command key paradigm, I think it would make a lot of people happy.

Shift+Insert will let you paste anywhere. It's an IBM thing historically, I believe, and it works pretty much anywhere. Also useful for websites that try to block normal ctrl+v.
