I think it would be safe to say that most people are having a positive experience on OS X these days.
Well I believe it's safe to say you're completely wrong. All I can say is: Yosemite in the App Store = rated 2.5 stars
The problem on this forum is that there's too many people who are bootlicking Apple no matter what. Sad souls.
But not every version of OS X is bad. If you don't like it, simply don't update. I'm using the latest version of Mavericks and I believe it is the best OS Apple has released. (using Apple since ever never had something other than Apple)
We also have several other Macs that are over 10 years old in our House and they work fine for normal stuff like surfing the internet, printing stuff, importing pictures, a little PhotoShop, writing emails
I don't understand why people always want the latest. Especially in these days where everything is rushed at Apple, you would definitely not want to upgrade to something like Yosemite.
Although I must say, I did not have any issues with the first versions of Lion, Mountain Lion and Mavericks.
