What is your favorite Calendar App? (OS2008)
 

No worries, this will be the last app poll from me :)

The previous two ones;
- Your favorite ToDo App, and
- Your favorite music player

were, at least for me really valuable and in the end they caused me to discover a new music player (Quasar) and try out a, to me; different todo app. Hopefully someone else out there found something new/different from these threads to try out.

So, what IS your favorite calendar app (OS2008)?
