OS depends on function.
I use:
Windows 7 on most desktops and laptops
Centos for phone server and infrastructure monitoring
Omnios (Solaris fork) for mass data storage, media serving and such (ZFS file system can't be beat)
android for phones
Looking with trepidation at the upcoming Windows 10 stuff/crap. Not a fan of the flat UI, but I'm a stick in the mud, I'm sure.
