SlinkySausage writes "Google is offering ISPs the opportunity to turn over their entire email operation to Google, with all customer email hosted as Gmail accounts. This would allow Google to grow its user base rapidly (Google is a distant third with 51M users compared to Yahoo's 250M and Hotmail's 228M). There are some obvious benefits to end users — Google is offering ISPs mailboxes of up to 10GB per user. APCMag.com has posted an interesting piece looking at the dark side of Google's offer. Not least is in its reinforcing of the attachment people have to their ISP's email address, making it harder to change ISPs if a better deal comes along."
