Well, that's not too far removed from the plugged-in laptop with the
wireless still active.  Toss-up which one wins default route.

What would you "like" it to do?  BGP feeds from both (likely not
happening)?  Defaults from both?  Or you just want active/passive failover?

The real-world case for host routing (IMHO) is a server with a public
interface, an administrative interface, and possibly a third path for
data backups (maybe four if it's VMware/VMotion too).  Unless the
non-public interfaces are flat subnets, you need some statics (today). 
It can be a challenge to get SysAdmins in a co-operative mindset to
route that correctly (and repetitively if you have a server farm).

I would be walking the fence on the virtues of automatic route discovery
in that case versus the security of static routes/configurations. 

But home use from a host perspective?
