While it cant be argued that Google is a great search engine. Serious overhaul of their sponsored link program is needed. There are many scam/phishing/FakeAV sites prominently advertised by Google sponsored links that do nothing except make the internet malware problem worse.
Very good, maybe the best free E-mail. Good security of viruses, malware, phishing. There is no advertisments and it looks great. Unfortunatelly Google can't provide privacy as well. (please read EULA).
About search engine, I think Google is the best.
I no longer trust GOOGLE because I believe that it collects private information for profit and it has almost become a monopoly, which in my book is a bad thing. I believe that their software communicates with each other, sort of interconnected. I use to love it before it started showing up everywhere. There are too many scams and identity theft going on for one enterprise to have so much information on its users.
