I recently took a major personal and professional leap: I switched to Windows from Mac, after nearly 20 years of being a dedicated Apple fan-boy.
I have been a Mac-addict since 2002, when my then-new employer at the time allowed me to acquire whatever new computer I wanted. MacOS X had just been released, with much buzz and hoopla. I chose Mac as an act of defiance, a repudiation of what I perceived to be an oppressively conformist Windows environment. It was also a nod to my past; my first ever home computer was an Apple II+, purchased by my father when I was fourteen.
