Is anyone here using either or to provide free web-based email to your visitors?

I was wondering if you are happy with the service or not.

I'm also wondering if people even like web-based email. I don't mind it if I can also use a POP3 program like Outlook. Web-based email allows me to check my messages when I'm not at my computer, but if I had to used web-based email exclusively, it would probably get old.
