Don\'t people just use their ISP email? People really use yahoo and hotmail? I don\'t understad why you need hotmail if you have an ISP.
It\'s all about security and spam.
i only give out my ISP email to familly & friend.
When i registrer to websites, surveys, blablabla it all goes to my Gmail account.
Gmail as auto spam feature, that classy spam email into a quarantine zone. you can still view/open those email, and unspammed them. (and you can "add spam" email that you receive)
so you keep your ISP email clean. less chance of virus and such.
You read all your other "stuff" on gmail (or others..) at work, outside the house
