Following on the topics of using iCal with the Exchange server. AppleInsider published a very interesting comparison of iCal and Mail.app to the coming Entourage 2008.
The AppleInsider Article left me very upset, as it is evident that there will be no improvement to synchronisation with iCal. Hopefully Office will become much faster, as it will be compiled as a universal binary...
The only remaining hope is for Snerdware's GroupCal. Guys from AppleInsider got it wrong, as GroupCal is not yet working with Leopard. We have to wait a little, and hope that the developers from Snerdware solve their problems and release a new version soon.
Forget my complaints about the price. I will buy the new GroupCal on the first day it is released.
