I'm just upgrading to a dual G4 and OSX, and I have Office X. I'm wondering about iCal vs. the calendar in Entourage, and Mail vs. Entourage for e-mail. Regarding e-mail, I run a one-man design shop, so I send & receive a lot of big attachments. Other than that, I don't think my mail needs are particularly special. Regarding calendars, I'd like to sync my calendar with my wife's over the LAN. As far as I can tell, I'd have to get a .Mac account (and another account for my wife?) to do this with iCal. I can't tell yet whether Entourage will let me sync calendars via our LAN (stupid MS documentation). I love Apple's software, but if it can't do the job (yet), I'll use MS. Any recommendations?
