On the other hand....
I subscribe to a bunch of technie mailing lists & it gets annoying to have some that I only subscribed to so I could post once and ask a question & was too busy/lazy/whastever to unsubscribe from the mailing list right away.
With Gmail I assume I could sign up to 100 of those lists and have it all properly filtered into folders without worrying about the email account being disabled by going over the space allocation (

hotmail)
Then when I need to post to the list, I'm already signed up and authorized to do so.
hrmmmmmmm I suppose I will be getting a gmail account after all.
