How often: upgrading operating software platform

[Maye]

I have a Mac Book pro and I found that the the OS is easier to upgrade than for a Windows based computer. Drivers that are required for printers to work properly get installed automatically versus having to do it manually like with a Windows based OS. I'm not sure if this is still the case with Windows 8. I do upgrade the OS if major updates or features are added otherwise, I usually wait until I have no choice or when major security issues require me to update and or upgrade.
