I really do not like google's policy on updating. It presupposes that any organization has a lot of bandwidth and doesn't mind updates going off at inconvenient times. Since one of the places I work at has a couple labs of Macs and does video classes on the same internet connection, I see a real annoying situation.
Yeah, well Google Earth isn't. This is where Microsoft and Apple have a clue. Let sysadmins have a central internal update server that can be controlled.
