So the protocol seems to be that strong web platforms want to themselves loosen up their dependence on their OS platforms: browsers, operating systems, etc..., so taken to an extreme the right thing to do is build a hardware platform? A little extreme, no? It makes for a good plan B, but who thinks that creating yet another competing platform in the mobile space is a good thing for Facebook, at this point? Right now they have a very comfortable position on iPhone, Android, and Phone 7, with the biggest risk for platform subversion coming from Google. That still leaves them two viable platforms on mobile, with virtually no conflicts of interest coming from Apple, and possibly none from Microsoft either. (Okay, Ping, but I don't think Apple's ambitions for Ping are anything beyond boosting iTunes sales.) Now not only will they introduce another platform, but they will turn their existing platforms hostile against them. It's the kind of behavior that will land Bing as the default operating system in future releases of iPhone. Possible responses: a Facebook phone OS might push Google to do a deep Google Me integration into Android, thus forcing most Android users to at least give Google Me a try, which hurts Facebook. It might force Apple to make Mobile Me free, and then integrate deep photo sharing and commenting into iPhoto and iOS. Since a plurality of college students own Macs and iPod touches already, Apple has very powerful platform control that can cause trouble for Facebook should Facebook be perceived as a threat to iOS. I don't see either of these response scenarios being particularly profitable for Facebook. This can get very, very nasty. As they said in Godfather, "Nobody wants all out war."
