actually they're changing the OS X model to follow that path of iOS - yearly upgrades and faster cycle which will actually keep OS X more up to date.
I personally see nothing wrong with adding features like Notes, etc - its better than them not being there.
Yes I can see that.. it's an idiotic move in my opinion. There is no purpose in rushing out numbered entries of OSX every year if they add tiny and insignificant things. It just diminishes the credibility of the operating system.
These features could be added via a software update OR via the App Store. These are simply apps.. there is no need for this to be called "Mountain Lion". These titles should be reserved for significant interface revamps.
Adding a notes and reminder app among other things isn't a significant update. I can already make notes on my laptop.. why do I need another App called "Notes". Why can't they incorporate Notes and Reminders into a unified App?
It's just becoming so tacky and crowded.
