If google made their operating system free they'd be throwing away multi-billions. Plus it'd be stupid IMHO for Google to make an operating system. Apple, Unix, and Microsoft built the operating systems they have now off of every other operating system they made since the 1980s. If Google were smart they would make a deal with Microsoft and help Microsoft make a better operating system. But then Google would either automatically become Black Hat because people hate Microsoft. Heres what every corporation, even Google is about. Getting on your good side and then stealing your money. Google has been pullting a BS scheme where they make free applications but those applications can be easily used as spyware. The thing is since it's in the source of the applications no anti-adware applications would see it as a harm. Google desktop search can easily be used to see what files you have, like what music you listen too, what food you like, your intrests. Google Web Accelator literally takes copies of websites you go to (even control panels and stuff) and caches them. What better way to find out what people think is popular and help Google find a way to get a deal with the popular thing and get cash. Gmail can beused to keep a record of your email. It could easily be looked at by Google and give write a deal with a company that fits your intrests. Basically what I'm saying is, Google is making backdoor deals with companies to get tons of money because they track what the public likes with their free applications. This is just a personal theory but who knows, how did Google get enough to pay for 250,000 servers and over 1 PetaByte of data storage? Just to give you an idea of how much space Google has just for Gmail, lets say there are 1,000,000 gmail users. They each get 2.5gb. That's 1mil times 2.5 so 1,000,000*2.5. That equils 2,500,000 of course. But when you convert 1 million gigabytes to a bigger standard you get 2,500 Terrabytes. A Terrabyte is 1000 gigabytes. So that means that You have 2,500 Terrabytes, so what do we goto? We go to Petabytes. So that would be 2.5 Petabytes. Saying that only 1 million users have gmail is under estimating. Google could easily have 10 Petabytes. And with Infinity+1 it'll soon be up to 3gb per account. So then we'd have well over 2.5 Petabytes. So unless Google is not really giving that much space unless needed they have to be making deals we don't know about. Edit: I accedently put web browser instead of operating system.
