Gmail is the first web email service that offers 1GB of web space to store all your junks and attachment. I use it all the time. It is quite reliable. There are a couple of times my mails get gobbled up without warning as I send some Visual Basic .NET files over, but asides that, it’s no problem.
I wouldn’t recommend people to use it for their work if you trade source codes often though.
I just hope this isn’t an April Fools’ joke. April 1st has some more important event for me though.
In the meantime, if you can’t wait for a Gmail account, I can always invite you!
