I’m another wishy-washy go back and forther. I’m now on Mail but used the last version of Entourage for a couple of years. I did the demo thing with the 2004 revision and have to agree that it’s an excellent program. However, I don’t use it.
The main reason I don’t use it is because I’ve fallen in love with services aware small applications that tie Mail, iCal and Address Book together and make the data available in other interesting ways. The Services menu makes it easy to send selections out of Cocoa apps to Mail. Yes, I can copy and paste into Entourage but ever step takes time.
Entourage has more features, but Mail is good enough and the ability to connect with iCal and address book via third party programs more than overshadows the goodness of Entourage as an email client. And, I’ll me-too the sync problem. Even with third party help it just doesn’t sync reliably with my Palm or between my Macs or with my cell phone. If you use the rest of Office then Entourage is a good choice. If most of your work utilizes other options then it isn’t.
I’m a web designer and use iBiz to keep track of my projects. How do I create a new account? In Address book. iBiz links well with a sister app iBank that is much more reliable than Quicken. Where do I keep my working files? In DEVONthink, which is happy to import and sync my mail and addresses for convenient backup.
iCal is my main control center for automating recurring timed processes. I use Audio Hijack to save streaming audio so I can listen to it at more convenient times. I use Yummy FTP to keep web sites backed up. Both programs are happy to take their instructions for when to do their tricks automatically from iCal.
iCal also makes it easy to publish multiple calendars, one for my MUG, another form my photography club and another for family.
I tried Eudora for a short time. I used to use it on OS 7 - 9. It may seem silly but I won’t use it because it’s ugly. If that doesn’t bother you then give it a try. The sponsored version is free and full featured.
Finally, when I did use Entourage I also used Emailchemy to convert my mail out of Entourage’s database into a savable format. Backups are good. It’s a very worthwhile $25.
