Tramp is how I finally got over the chronic problem of having to use vim just for remote editing files on remote machines over an ssh session. It does sometimes hang and chug inconveniently, but dealing with that is far easier than delicately holding a config file like a flower while I remember the precise vim commands (and work around the TTY special code interpretation issues that break arrow keys) to make my edits to one line.

N'ah, forget that. It's worth the setup time to make Tramp go brr.
