what do you do when you have 100B+ money at hand and the market expects you to turn 100B into 200B by some magic: you become an investor. Companies like facebook themselves have basically become some kind of high risk stock broker. I predict another stock market crash in 2015-16 timeframe.
Oculus has the potential to change the world and facebook just wants to change the way we use this new technology and the gaming industry trends. We will now play Candy Crash Saga instead of quake in VR.
Let's all wait to see what will really happen, no need to cry yet.
edit: no I don't defend FB I don't need the Occulus at all, but people have been reacting like it's the end of the world, smh, speculations all over the web, calm down.
