I have been and avid pc user since 2001. I never even thought about trying anything else. Until a little over a month ago when I purchased my first Mac Pro. Wow what a huge difference between the 2 . I'm so used to my computer crashing or getting attacked or infected with some type of virus, malware, adware etc. You name it my Dell's probably got it. I have to admit I was real ignorant of Apple computers in the past. Now, since the switch I can't believe how worry free I am, and how much money I've already and will save . I'm also SHOCKED by all the features. It's a "WHOLE NEW UNIVERSE" with Apple.
