Former windows user, mac user now for more than 2 years now. The moment i switched my life changed completely, simply because i produce music and a photography hobbyist, everything became so easy
I recently switched to Ubuntu 12.04 on my desktop, having previously ran Windows 7. I've had a couple of Macs in the past but much of the software I want to run just doesn't work very well on Mac OS X. I also like having a system I can tinker with, which neither Windows nor Mac OS X allow much of.
Use both. Started teaching at the HS level on the AppleIIe,then the early Macs. Our business community influenced our next choices - Windows 3.11 et. al. on Radio Shack, IBM and various various other PCs. I never imagined anything like my IPad which I think is SUPER.
Music is the last thing I use my mac for but a lot of people buy the macs and then install windows on it, the track pad really makes it easier to surf the web with, I could never go back to a laptop with out it now. though I have windows machines as well, always have the best of both worlds, ios devices android windows phones..etc
