"It could become an irritant," Wolf said. "There's a class of people who, for lack of a better word, 'live' on Facebook. If you use Facebook exclusively, then there might be a call for (dedicated phones), but it's a minority, a small percentage of people who use mobile phones."

"I don't think I will buy a (phone for) Facebook since all the rest of the phones can give me pretty much the same," he said. "I think Facebook is somewhat losing popularity now, since my Facebook and some others are extremely quiet.
