When I vi a read-only file:

     "/etc/mail/aliases" [Read only] 36 lines, 1023 characters
Its simply a matter of remaining keen when doing admin tasks. Sure I have to close/re-open with sudo but its prompting me up front that I won't be able to save it.

No, you don't, and yes, you will:

  :w !sudo tee %

You can do something like this instead (IIRC):

    :w !sudo tee % > /dev/null
It's a bit of a hack, but it works.
