Didn't you also bring that upon yourself by buying a product from that particular vendor (Apple) as opposed to any other? Upgrade treadmills and forced obsolescence are always a risk with software, and users need to learn to account for it.

I recently acquired a Macbook Pro from work, but I'm using Windows 7 on it full-time. I'm far too wary of being forced to upgrade when Apple stops providing security updates to the version of OS X currently installed on it.
