What happens if you plug in more than one device like this? I know
people who sync more than one palm device all the time.

Good luck, writing a rule for all palm devices is _hard_, if not
impossible due to the wide variety of devices, and what port is supposed
to be used for syncing with (some devices lie about this, and you don't
know for sure until you try to actually sync with them.)
Marco did the right thing in closing this :)
