Kirill, we have all been Microsoft's galley slave/hostage for the last 20 years. Microsoft was a lot more Evil at times than Google has ever been.
Despite the FUD campaigns waged against Google by MS and others I have found Google to be
very careful about what they do lately.
The two very bright kids that invented Google have grown up some -- literally. I think they did do some stupid things back in their mid twenties (things they wouldn't do now they are 30 somethings) The things they did weren't illegal, just unexpected and way out ahead of the curve.
When somebody said, "Hey, you have to pay for that !!!" they ponied up along with an apology. (I wouldn't have thought scanning in out of copyright books made you owe anybody anything either).
Google is about data, information and advertising. That is what they do.
I think they still take risks though (Loon and HyperSpeed Internet for two examples) but I think they weight taking those risks out better now.
Selling off Motorola (carefully, so as not to damage it) after impulsively buying it was a sign of growing maturity for them.
Let's talk about Chromebooks and Boxes -- is there any personal information they or anybody else are going to gleen from you off those platforms that they (or somebody else) hasn't already mooched off you already?
As far as Larry and Brin suddenly deciding to pull the plug on the server farms on you -- that isn't going to happen without them going broke and then going to jail over it. Google Services are wide spread throughout business and industry -- people like us running ChomeBooks & Boxes are just a small freebie add-on to the real Google Server Empire.
Besides, they have carefully made sure the hardware will support general Linux Distros as local loads. So if they did tank, you'd just shift OS systems.
Current example: Google is investigating becoming an ARM chip designer (full design license) so they can design their own private use GoogleServerFarm chipset.
Right now Google buys more server racks than anybody else in the whole world and their energy bill
per month exceeds the GNP of some small African countries. They are teaming up with IBM and the ghost of Calera (recently failed start up) to try to do this ....
If they had been Microsoft they would have run Calera out of business intentionally by partnering with them and screwing them over .... then bought the pieces but kept the corpse separate so they can cut it loose later. (sound familiar, Nokia?)
Google will be a much gentler plantation master than Microsoft ever was. If I had to be somebody's wage slave in the computer industry, I'd pick Google over MS or Apple. Google feeds you for free and gives you ping pong tables ...
But then again, I quit being anybody's computing slave a while ago .....
(although I do admit to liking a little sprig of mint in my glass of sweet tea, that is a
preference, not an addiction).
