In Calendar Agenda you can "zoom", but even then the screenfonts are very big so you see (in weekview) only a part of the appointments. The possibility of zooming on a Psion Revo is comparable but much better. Is there a possibilty of changing the fonts for Calendar?
Screen fonts in Calendar
I'm fairly ceratin you can't, i thought this could have been 'fixed' with the ROM update as I have seen so many negative comments about this, but alas simple consumer demands seem rarely satisfied by Nokia.
It's ridiculous that the smallest font view is so big that you can't have more than possibly two words on the screen!
You're right, you can't zoom out enough. After coming from a Psion 5mx & Revo myself I have been a little disappointed with Calender.
But, the good news is that I've just been trying 'Powerdesk' from Symbianware and it's much better. There's also a cheaper version called Powerday that lacks some extra features.
