Computer World - Gmail users have been sucking up space faster that Google can add it. Google announced that due to increased demand, it will be increasing the speed at which it upgrades storage space on its web-based e-mail system. Right now most Gmail boxes ar about 2.9GB, but that will soon change. Google is having to strive to keep up with Yahoo and Microsoft, who are offering unlimited storage and 5GB of storage respectively for their web-based e-mail clients. Gmail has been immensely popular since its release in 2004, but it has since met stiff competition from other companies, and is needing to adapt to regain its former place.
