Is there really space for facebook in the mobile operating system and browser realm though? The way I see it facebook's best bet is NOT to try and make its own phone and operating system, which is way beyond their specialty and current capability. No offense to all the web-devs here but web programmers are not operating system programmers in the same way operating system programmers are not web programmers. Not to mention the hardware side of what it takes to make a phone (although they could outsource the hardware to another company similar to the way the Google Nexus program works).<p>Instead, in my humble-yet-broadly-assumptive opinion, the best R.O.I. for facebook would be to try and lobby for greater integration in the phones and mobile operating systems that already exist rather than try and reinvent the wheel on their own. I think they missed a major opportunity by not becoming integrated in the iPhone (losing out to twitter), but I don't think they entirely missed the boat there. If any platform opened up enough to allow facebook to become a viable way of sending messages, finding contacts, and sharing photos and the like, it would not only provide a valuable user experience but also prove profitable for all parties involved.
