The bang is required for the 'w' command if the file doesn't have the 
'w' bit set. Try it as any "normal" user - and then try to edit/write 
the same file as root:

touch file
chmod 0100 file
vi file

and see what happens.

The "x" command is convenient shorthand for ":wq" (although writing only 
occurs if changes have been made). Even that needs a bang on the end if 
the file is read-only.
