Same here, Jay. After a few years programming IBM mainframes, I moved to PCs in around 1987, and have used Microsoft products ever since in a professional capacity.
I switched at home to Macs in 2008, and wouldn't go back - although I very happily use the OS X versions of MS Office.
Fortunately my current clients have rolled out Windows To Go for consultants, so I get to use my beloved MacBook Air running Windows as a guest VM, which is nice.
