Yahoo! used its annual financial analyst day to announce an expanded email service. With Google's beta GMail service grabbing so much attention, Yahoo! will expand the amount of free storage to 100 MB per user over the summer, and a rather vague promise of "unlimited" storage for paid users. GMail will offer 1 GB of storage and a vastly superior search capability. 100 MB of storage in Yahoo! Mail currently costs $49 a year.
