Facebook placing itself to hit Google and Apple at the sametime.

Here are the two interesting news from Facebook -
1) Facebook is trying out a technology to trace your cursor.
2) Facebook is in talks with Blackberry to see if it can become a device player.

Now connect the dots.

Currently, Facebook is trying to trace cursor for Ad improvements only within Facebook - But in future, after becoming a device player, (if successful) Facebook might trace cursor whenever you use the device.

But then this is just a smaller shine in a bigger mine - Transition of Facebook into a product company will entirely change the game with closer integration of facebook into a device- fmail, fcalendar, fmovies, fmusic, fstore, fapps etc.
