I received an invitation to use Gmail recently, and have signed up for an account. I am just amazed by how nice it is. It isn't just the 1 GB of storage that amazes me, but the user interface that I find impressive. It's very fast, powered by some form of javascript, apparently written specifically for use on this service. All in all, I find it to be unequivocally better than any web-based email I have ever seen. When I get some invitations to give away, I'll work on weaning my friends off of hotmail.
