Of course that only applies to Google Apps and not @gmail.com addresses.

But good point, and I reckon that's another good reason for anyone using email for professional purposes to get their own domain and use it.

(One of my pet peeves is seeing businesses advertise a www.mycompany.co.uk website and a bob@aol.com address. Small places do it a lot - why would you buy a domain and not use it fully? Why?)
