Google is not just a search engine or an advertising agency. From my perspective, I see a number of free services are now offered by many others that would have never been offered for free before Google establishment.
Further, you can't really find a good alternative that offers clean, simple and almost error free services like it. For instance, look for any advertising agency that offers a service better or even like google adsense. The fact, you will not find!
Any alternative search engine that is so user friendly and extremely fast with a country or global search? Doesn't exist to be honest. Although Bing is the 2nd but I tried many times to replace Google with Bing, mmm, didn't work for me.
Google on the other hand is investing a lot of money in serving the earth and humanity. We have seen Google glass, Google internet for poor areas in Africa, Google car, etc. This proves the fact that Google is one of the best companies around the world, ever.
How many of you benefit from Google when searching for a topic, translating a word, searching for a service or even a restaurant nearby?! Now, you want to leave?!
