I don’t think you will be able to review the services of google.com but instead you will only be able to praise their serviceability.They are extremely good and popular, who else provides you 15 GB storage per account, and that too for free and premium quality customer support for free users.
Android was the greatest contribution of google, gmail is now the acronym for e-mail, google is the acronym for web search.Google is really changing the way we used to look at the web.And their new initiatives like google balloon will be tomorrows free internet.Thank you google.
