For me even that's annoying enough. On a mac it's consistently command-x command-c command-v everywhere, whereas in Linux I have to think "oh, I'm in a terminal now, use shift", and if you get it wrong things screw up (e.g. C-shift-v opens the inspector in Firefox if memory serves).

Same here - I didn't know that Linux copy-paste still had problems, but that could be just because of how we're using it.
