I would prefer to use Apple software as much as possible. Especially instead
of Microsoft. But I can't find much fault with Entourage which does
newsgroups and has a built in calendar, as well as full mail functionality
all in one application.
Apple forces me to run four applications for the same functionality: Mail,
iCal, Address Book and a newsgroup reader. Apple Mail does not do newsgroups
I discovered. While the integration is good it clutters up the Dock to have
to run them all.
I'm not a big fan of Microsoft, but they seem to have done it right....
