As part of google apps, it's a mediocre solution. It's not good for collaborating with people outside your organization (clients, patients, whatever else ends in -ients) but it's just good enough to prevent me from going with a hosted Exchange solution or to go back to administering our own infrastructure. I suspect it's prioritized to remain at that level.
