Google GMail Review

As promised. If you don't have a webmail account, look no further than Google's offering. While currently invite-only, it has a feature set that exceeds most other providers.
2.5GB storage. Never delete email again (which is just as well because you can't).
Efficient web interface. The best webmail interface I've ever used, it offers keyboard shortcuts, and preloads everything to make navigating around your account more responsive. You have to wait a couple of minutes to sign in on dialup, but after that it's good.
POP3 and SMTP access. Use any standard email client with your account. Some nifty features here include the ability to download copies of messages sent via the web and that Google uses a nonstandard port to send mail getting around the blocking some ISPs impose. Both connections are also secured.
New Send Mail As feature. Verify your ownership of other email accounts and Google will offer to spoof the identity of outgoing email. In combination with the access from any email client or web browser, you can now manage your own identity. Send from your old accounts.
Integration with other Google services. Including the new Google Talk and google.com/ig portal.
My verdict: there's no reason not to get GMail at this point and no-one else comes close in free functionality. Comments? Also, I have invites!
