It's not going to work
Zuckerberg would've done better to design a better Facebook App for all platforms that actually works well and is pleasant to use based on what FACEBOOK USERS WANT, not what he wants to shove down their throats. Everyone keeps trying the Steve Jobs approach without realizing that he's the only one that will EVER work for. Zuckerberg would like to think he's got the mojo of Jobs, but no one in the tech industry does. Facebook Home will fail miserably because, as others have pointed out, no one, including the most obsessed Facebook users, wants their entire phone experience to be Facebook. No one. Sure, some will download and try it and sure, some will even buy an HTC First, but people will quickly find it more annoying than the Facebook Timeline and rush to uninstall it more rapidly than they installed it. Besides, as has been pointed out, none of the big players in the industry will want Facebook Home to succeed in taking over the user experience. That alone guarantees Facebook Home's failure.
