> If like me you came to Apple as you had no interest in upgrading a machine, ever, at all, then they've not changed.
Not true; at some point in time versions of OS X kind of stop working (no new version of Firefox or Chrome for you if you're running anything prior to 10.5 for example).
Sorry, I should have been more clear about hardware upgrading versus software upgrading. But you do raise an interesting point, as Apple progresses their software so do companies, so if Firefox and Chrome no longer work then is that the responsibility of Apple? I'd say no, and I'd say OS X 10.5 is still a mighty good OS with excellent features throughout, but I don't blame FF and Chrome for moving forward.
