Sometimes I'm using the wireless for "real" network access (default
route) and the wired to access a router for configuration or something.
NM takes a default route from wired before wireless (unless this has
changed recently and I missed something), so the only way to do this is
to shut down NM (and configure things manually).

I periodically use two or three wired interfaces, and again, I might see
a default route on more than one, but I need to control which one is
really default.  Also, sometimes I bridge between two wired interfaces
for traffic monitoring (since the cheapest gigabit switch with port
mirroring is ~$100).

My notebook (Thinkpad Z60m) has built-in gigabit and ABG wireless.  I
then have an ExpressCard gigabit and USB 100 megabit NICs for debugging,
routing, etc. when connecting to multiple networks.

I don't speak for anybody but myself - that's enough trouble.
