What would make a company that has no "real" assets that valuable?
Their brand alone is a valuable real asset. The data mined from their users' profiles is for the most part very real, as well. Most of the value lies therein.
didn't the PS3 and Xbox 360 cost more to make at launch time than they were selling for?
GM should have built an augmented reality gaming system into the windshield so they could make up the loss by selling new software.
If they would build such tech into web browsers as easy as checking a prominent preference button it could make a huge difference in the ability of governments to repress their people.
It would be easy enough for these countries to simply outlaw use of such browsers. Sure it would be harder to enforce than blocking individual sites, but it would only take a couple dozen public stonings for the masses to capitulate.
It is easier to write an incorrect program than understand a correct one.
