5 April 2013Mashable:
A floating picture of a friend’s head appears on the screen — their Facebook profile image — and can be dragged via your finger to anywhere on the screen. You can tap it to open a message window, and more than one chat head can be on screen at one time.
The floating icons appear above the active application. It means you can carry on chatting without having to bounce between applications.
I need to wait and see how intrusive they are, but based on the preliminary glances shown today at the event, I think they are cool.
However, in order to have Chat Heads, you have to download all of Facebook Home, and I definitely don’t want to sacrifice my whole home screen to Facebook for the feature. I want Chat Heads to be offered unbundled, but this — obviously — does not correlate with the interests of Facebook.
