I would like to propose leaving Save icon's behavior unchanged for now since 
we would need more studies on various user scenarios including Kohei's one.

For instance, current behavior around Save function is too simple and is not 
capable of avoiding overwriting a document file. 

 Scenario A
  1. User A ) Opens a document file X on the file server.
  2. User  B) Opens the same document file X on the file server.
  3. User A ) Starts to modify it.
  4. User  B) Starts to modify it.
  5. User A ) Saves it.
  6. User  B) Saves it. 

What will happen? The efforts done by the user A will be completely lost by 
user B's overwriting the file. No warning will be reported. How can we avoid 
such a situation? File lock? Maybe no. File lock sometimes causes more 
complicated problems. If an application software on a laptop PC locks a file 
on the file server and then the PC's Ethernet cable is unplugged, how can we 
unlock the file?

The editor Emacs gives us a good solution. It seems to use a time stamp of file 
or something else to find if a file has been changed. 
On the above user scenario Emacs will warn at step 6 prompting 
"X has changed since visited or saved.  Save anyway? (yes or no)"

 Scenario B
  7. User A ) Opens a document file X on the file server.
  8. User  B) Opens the same document file X on the file server.
  9. User A ) Starts to modify it.
 10. User A ) Saves it.
 11. User  B) Starts to modify it.
 12. User  B) Saves it. 

Emacs will warn at step 11 prompting 
"X changed on disk; really edit the buffer? (y, n, r or C-h)"

So user B will be warned and given a chance to choose what to do. Where 'r' 
denotes 'revert' - the contents of the buffer are refreshed from the file on 
disk. 'C-h' means pressing a key 'h' with holding a Ctrl key and shows a help 
message. 

If user B answers the prompt with 'y' and moves on to the step 12, the user 
will 
be prompted with the same warning message as the step 6.

So what i want to say here is that if we try to change behavior of the Save 
icon 
button, its specifications could be somewhat more sophisticated to cover 
various 
user scenarios, especially for enterprise use. 

Please, please do not jump to quick conclusions.
