Although both companies will deny it vehemently, it is obvious that Google's Gmail service has caused Microsoft and Yahoo! to re-evaluate their email services. In response to Gmail's 1 Gigabyte Email service, Yahoo! recently upgraded their service from 4 MB to 100 MB. Now, Microsoft has announced that their Hotmail service will be upping their threashold from 2 MB to 250 MB. Both Yahoo! and Hotmail will also give users the option of upgrading to 2 GB of space (twice what Gmail offers) for about $20 per year.
