After reading about it on Slashdot, I tried out Sunbird, a great calendar application from Mozilla.org. I was quite impressed with the program. I was able to subscribe to my iCal calendar, published via WebDAV from my Mac at home. In this way I can see the calendar entries defined on my Mac at home when I'm using my ThinkPad in the office or on the road. That's very convenient. The pretty new icon was designed by Mark Carson.
