Google.com as per title you have to have present for internet different activity.When you are doing any activity like searching something, down loading, uploading, emailing, finding maps etc.
You need Goggle.com. There are so many like mozilla, bing, yahoo are in line with Google.com to provide service like Google.com but still Google.com is number one in providing same type of service.So as per my view. google.com is heart for net activity . everybody have to get it in one or other way.
