But I would point out something much more important : there are many
more local exploits than remote (on Windows just like any other OS).

Local exploits : about 1-2 a month
* POSIX - OS/2 subsystem exploitation
* Debugging subsystem exploitation (DebPloit)
* 16-bit subsystem exploitation (NTVDM)
* Shatter Attacks
* Etc.

Remote exploits : about once a year
* RPC/DCOM (blaster)
* LSASS (sasser)

Basically, if you are logged in as an unpriviledged user on a Terminal
Server, you can easily become SYSTEM. If this Terminal Server is also a 
Domain Controller, game over.


You forgot one important factor - the use of IE and Outlook for the fast
direct-to-customer delivery of local exploits.  Which *also* results in
a Game Over....
