It's amazing how much Google has upended not only the market for, but our expectations of "Office" suite products. When I first clicked the "share" button in Pages, I was actually expecting an "invite a collaborator" option and was disappointed until I stopped to remember what a massive infrastructural achievement Google's real-time document collaboration system is. I'm sure such functionality will eventually come to iWork, and it's undoubtedly very impressive already, but it's a reminder of just how wide Google's lead is at present.
