Nothing is Free, Not Even Android

Remember that feeling you had when you bought your first Android handset, thinking you had just walked away with a steal, a great operating system, which happened to be priced just right, free? Well, Android is just about to get a lot more expensive to the phone hardware manufacturers who choose to use it. First it was Microsoft and now Oracle wants a piece of the pie. You can be sure that when they are through, Android's competitive advantage will be severely blunted. The ball is your court now, Google, keen eyes are watching.
