Some people who claim they have no issues must be delusional apple fan boys, have memory problems, or are simply noobies to the world with no experience with what was once the norm, that being, stability and efficiency. Snow Leopard comes to mind and that was some time ago.
The days when Apple used to focus on stability and simplicity are long gone. The reality for me is that Mavericks has taken a back seat to my Windows 7 install. Pretty sad but true.
It's strange that the OP's join-date is the same year that Vista came out since I otherwise would have a sworn he must have been too young to have been around for Vista.
I'd just like to note that Vista ran flawlessly when I ran it on a MacBook Pro. It was only on a PC that it gave me any trouble.
For the record, I'm 78, been retired for almost 20 years and have been involved with computers both as a hobby and in Industrial control since Radio Shack came out with the TRS-80 model 1.I believe my join date is around that time too. I actually switched to using Macs and OS X because of Vista and how bad it was. Vista prevented me from doing any actual work. It turned my computer into an enemy. I had to fight with it to get anything o substance done. And I spent $400+ to be among the first to get it, and completely wrote that off as a loss.
That's never happened to me on OS X, from Tiger to Mavericks. Lion was pretty bad, but the issues were annoyances, not show stoppers. And yes Mavericks has had some glitches here and there, but I've personally only noticed them once someone has told me they exist.
So no, Mavericks is not Vista, not even close. If the OP truly thinks it's that bad, I'm sure Windows 8.1 will make him quite happy.
