I noticed they had standalone Entourage packages at CompUSA too. I like Entourage, but in the past several months I've actually switched from Entourage to Mail/iCal/Address Book. I wouldn't have expected to switch from the commercial app to the ones that come free with the OS, but Entourage comes with a performance hit. I don't need Address Book and iCal loaded every time I want to be able to check my mail, and besides, I think Entourage uses more CPU time than having all three Apple apps open anyway. The Apple apps are integrated with each other sufficiently well that they can collectively replace Entourage for me, and as a bonus I like iCal's calendaring interface better. Besides, Entourage seemed to crash or cause problems a lot more than I was happy with.
