I've been on Windows 7 Ultimate for 5+ years and other than the complete dropping of support, it would be quite hard to convince me to go to a different OS.
My wife plays guitar, ukelele, cajon, keyboard, teaches piano, can sing, and composes music using pro tools software. Me? I can mix sound and play limited piano. That's about it.
Since I usually tend to look on my past as the good old days, it serves as a good reminder that we shouldn't dwell in the past, and should live in the present, every day to the fullest.
