I had mentioned this earlier in a comment left on another blog, but I have recently moved to using an iMac at work and away from my Windows laptop that I have carried back and forth from home to office for years. My wife, a lifelong Windows user said to me that I have moved to the dark side.
I did this with major trepidation, but I work in an office with 2 other mac users. When problems crop up I know I can get quick help with any problem. Every day so far I have felt like I am relearning how to use a computer. Don't tell my wife, but it has been a fun experience so far.
I am learning that the iMac has many quick ways to do things that took me much longer on the laptop. Also, as soon as I stop carting the laptop around so much, my elbow should stop hurting.
So far, the mac has tested me, but I have had no mac attacks yet that I could not handle. I am in day 2 without even opening my laptop, although it is still here at my side, patiently waiting for my return.
