GMail Utilities and Applications

Thanks to a blog entry by Chris Pirillo I have found this useful list of programs for GMail.

My favorite applications from this list are:
GTray
Notifies you of any incoming email messages to your GMail account. Program lives in your system tray.

Pop Goes the GMail
This appliaction sits between your GMail account and your email client, converting messages from the web based mailbox into POP3 messages that a program such as Outlook Express or Firebird can understand.
