Ha yes, learning vim was one of the best things I ever did. I can SSH onto a Juniper router and fix up config using vi. I still try to instill in juniors these days "Learn vim!" but everyone just wants to use nano (which I understand but nano isn't preinstalled on many network devices)

I do not understand.
I have a very capable colleague/friend who uses nano. Unix hacker type, so I think it is what he is used to from growing up. I still find it strange, but such is the nature of preference.
I also felt a little guilty when making the switch! Totally irrational of course, but still there's something to be said for sticking to the the original.
