I remember these guys going hell-for-leather at each other in public fairly recently. Surprise acquisition for that reason, but makese sound business sense I think. BlackBerry's going all-in on the enterprise. Apart from this Android phone thingey it's launching.
Interesting move by Facebook -- any developer can offer its service through Internet.org now in developing markets. Still, Internet.org is Facebook's way of getting millions more users for its own services. Maybe not a bad thing though if it can also get thousands more companies to sign up to this program.
