I was a PC user from about 1987 till October 2006. I love my Macs. Purchased a Mac book in October and was hooked. What pushed me to Mac was trying to run software on my Dell laptop for DJing - I had issue after issue. All my buddies use Macs and run the same software. I purchased my Mac, installed the software (I still can't get over how simple things install on the Mac), and haven't looked back at my PC since. Since, I have purchased a iMac 20" for myself and a 15" for my wife. I crossgraded my CS2 suite from PC to Mac (free) and even like using Photoshop on the Mac better. There are a few things that I've had to un-learn from my PC ways, but other than that I can't say a bad thing about my Macs. Also, if you are close to a Apple store, definitely purchase the ProCare membership, aside from access to free pro seminars, you can sit down with a Mac expert for one hour a week, one on one and talk (learn) about any issues or software on your Mac.
That's my 2 cents.
