I have always used a PC since they first came out. This is my first MAC and I can tell you it won't be my last, although I will probably keep it for a long time. I absolutely love it. It is super fast with a large monitor and it never locks up or knocks me out of a program and most importantly it doesn't take over when I am in the middle of something and update itself without permission and them reboot losing all my hard work.
What's great about it: Works right out of the box not two days later like a PC.
What's not so great: Sorry, everything is great so nothing to report here.
