Just received my iMac and learning how to use it. Have used Outlook for years on PC and also at work. I loaded Office 2008 and therefore have been using Entourage as my mail program. Question for long term iMac users: which is better, Entourage or Apple Mail? Before I go too far in learning Entourage want to know which program to use? Also, same question for Firefox or Safari. Used Firefox for years so any reason to switch to Safari?
