If you haven't heard, Gmail is now becoming the number one e-mail client in the world. The reason for this is simple, they provide their account holders with constantly increasing supply of storage space, and the e-mail interface is extremely simple and easy to use. The Google e-mail service is just like the Google search engine, there aren't ads placed everywhere on your page, and you are able to find the information (or e-mails) that you want in a moments notice. Thus, if you are constantly on the go, you want to be able to check your Gmail account wherever you are.
