I disagree. Browser, Office, and a keyboard make a pretty compelling argument for lots of people. All they really need is a Facebook app (which is integrated into the People Hub) and it's what most people will really want. Then they also have Messages (doesn't include GTalk, but different people use different things. A lot of the world prefers MSN Messenger over AIM for instance. And many people use FB Chat and Skype. It's not excusing MS for not having GTalk, but it does cover lots of use-cases and peole)
