While many consumers don't care what type of phone they're using, they do care about Facebook permeatting their entire user experience. For instance, Facebook writes of its chat heads feature:
"With chat heads you can keep chatting with friends even when you're using other apps. When friends send you messages, a chat head appears with your friend's face, so you see exactly who you're chatting with. Messages reach you no matter what you're doing — whether you're checking email, browsing the web, or listening to music."
Is that a feature or a threat?
