Web Mail is All I Need
I switched out of Thunderbird email client to web mail 8 months ago. I have been a full time user of our Zoho Virtual Office http://www.zohovo.com - online demo at http://demo.zohovo.com
It has been damn convenient, even when I am at home. I can check email from the currently-on machine real quick, and don’t have to download email anymore. While travelling this is a life-saver.
