Very cool stuff. Its rare that you see an ecosystem develop so quickly. Maybe I was wrong about GMail.

Gmail Tools I found some more interesting tools to make your Gmail experience smoother -

• G-Mailto: Sets Gmail as your default mail program in Windows. So when you click on a mailto:// url, your favourite web browser will open up a page with Gmail's Compose window. Pretty nifty.
• GTray: Windows system tray notifier for new Gmail mail.
• GmailCompose: A Mozilla Firefox extension to open the Gmail compose window with the click of a button.
• Gmail Loader: Import your existing mail into Gmail!
• Other supporting apps to help move to Gmail.
