When it entered the e-mail market, Yahoo provided just 3 megabytes of free storage per account. But Google changed the competitive landscape in 2004 when it introduced gmail with 1 gigabyte of free storage under its Gmail service. Gmail now offers more than 6 gigabytes of free storage.

I can't imagine having that much e-mail saved! But then, most of the e-mail I send or receive is without attachments.
