"It's been working properly for me and many others. If there was something inherently wrong with the OS, wouldn't it manifest on our systems?" Oh dear. There's so much wrong with that statement that I don't know where to begin. Maybe you should have just asked me to dig up my dead father and see if he's breathing after 4 years. After all, your father is still fine and they both had the same infection.
"If you are basing that opinion on the things reported here, there's nothing terribly different about this release from any of the others." You're not good at reading English or doing any research, are you? If you scroll back a few posts you'll find a previous one from me.
"Lots of people have lots of different configurations, both hardware and software. If the software or hardware isn't compatible, then you get problems." You have a very high IQ, don't you? *sarcasm*
"There are also changes to the OS that some people don't like." Yeah? Really? Like slow responses?
"That has happened on every new release. This one is slightly compounded by the people who chose not to upgrade to Lion or Mountain Lion, but did upgrade to Mavericks." Well, I ain't one of them.
"All the accumulated changes after Snow Leopard could be quite shocking taken all at once since the incremental changes caused quite a stir at that time." Irrelevant in my case.
Next time you post, try saying something mildy useful.
