I see your point, and it may make sense from that perspective - in fact, I would much prefer to return to the good ol' days of TRUE major upgrades every two years instead of these ridiculously disappointing paid releases that add little more than iOSified crap to OS X.
I still remember the days of System 7, Jaguar, Tiger etc. when we REALLY had something exciting to talk about when a new OS version was released, both in terms of under- and over-the-hood improvements.
What do we get now? Reminders? AirDrop which I've used only ONCE in like what, a year? Messages? Gimme a break.
The price of a new OS X has dropped hugely to accommodate the small features added...
By the way, with EVERY release of Mac OS there have always been critics about the new release.
It's just the way it works. The silent majority approves but many tech-heads on these kind of boards don't seem to like new features.
Remember when OS X 10.5 appeared? How much bashing there was about the new Dock? Some people hated Spotlight in Tiger when it first was available.
Apple is making iOS and OS X for the masses. Trying to make it as easy as possible, integrated with iCloud.
Apple is not using the same OS strategy as Microsoft. Apple is not about "support" or "backwards compatibility", etc. It's about trying to move forward, even by forcing new OS X releases on new hardware, even if Apple knows there are some known bugs. Apple wants all users to experience the latest new features.
Even if System Admins and Tech Support folk don't.
