Could be that IIS was installed and running by default (until
recently) on Windows desktops perhaps, making the available IIS
install base far larger than Apache on unices...
If there is a 50/50 split, whatever is easier to exploit will be
targeted. That may even be true if there is a 35/65 split, if the
gains to be had targeting a smaller number of servers outweighs
targeting the bigger section. Apache on unices (generalisation) tends
to be managed by people that are aware of security. This is not the
case for many Windows homeusers that may not even be aware that IIS is
installed/running on their desktop.

There is always two sides to the coin.
We are drifting OT here, so if anyone wants to continue this thread,
we'll use sounder or private mail - ok?
