I’m linking to the LA Times article about the NY Times article on the rumors Facebook is working on it’s own smartphone (I’m not doing this because I moved to LA, I reached my 10-article limit at nytimes.com):

Now, it seems Facebook is dedicating more resources to its phone project. The New York Times reports that the company has hired more than half a dozen former Apple software and hardware engineers and is actively recruiting others.

Ok, despite the title of this post, yes, you can buy talent, but you can’t guarantee it’ll stay around and it won’t guarantee you a hit product.
I would never buy a Facebook smartphone. I don’t want one company managing my relationships and monetizing them with contextual ads.
Apple manages my credit card with which I can purchase music, movies, applications and games. I am Apple’s customer. With a Facebook smartphone, I am not Facebook’s customer, the advertisers are. So like Google, Facebook’s goal is to please advertisers, not me.
No thanks.
