Some reports on the new Spotlight-enabled, sync-able Entourage are starting to trickle out into the blogging world.
Sven Semmler was delighted 
to see the latest service pack. He tried to use MailTags and Mail.app to organize himself after the GTD fashion, but found it didn’t work out for him.
Since moving over to try the new Entourage he is more than happy: “All I can say is: wow! Never before a service pack made me that happy. Big thanks to Redmond! You guys made my day.”
Michael at blindsquirrel.org also switched from Mail.app. Not that he was unhappy with it, just bored. He likes what he sees in the new Entourage but he does have one criticism:
The only weakness I see with the entourage syncing is that it can only sync with one calendar in iCal, and that calendar is a new one listed as entourage in the iCal interface. So if you have a bunch of calendars in iCal you have to switch their items over to the entourage calendar for them to automatically sync with the entourage calendar.
UPDATE: David Chartier at TUAW tells a cautionary tale about syncing his Address Book through the new Entourage. Ouch!
Now they need to break out their single Database repository. It scares me.
The update made me switch to mail.app. I tried to sync via the new entourage feature (used to use e2sync), it mixed up my appointments and tasks (duplicates and the likes) and trying to fix it purged my all-day-recurring-events (read: all the birthdays of my friends). switched to mail/ical/address book, now I’m happy again. and mail is much faster. :)
It’s one step up from junk now — I don’t know how anyone can be happy about this program. Yes, it adds some poorly needed features — but Entourage should be more concerned about taking some of the bloat away and focusing on user experience. Entourage does not make me more productive, in fact, I think the opposite, and this bandaid isn’t the cure all.
