Wow, there are some negative people on this forum.
Are you even running Mavericks? Your complaint about the "background image reset" bug would seem to suggest that you're not. If you "see nothing special" about Mavericks without even trying to run it, then you really shouldn't offer up a worthless, negative comment like that.
A fix to the "background image reset" bug you've complained about would make the upgrade "interesting" to you, surely.
I've been running Mavericks since DP1 and I can tell you that the performance enhancements on my RMBP are in themselves worthy of "interest." The latest DP is incredibly fast and responsive. For everyone that complained of UI lag, rest assured, it's gone. I don't see how things could run any smoother or faster at this point.
Is it really negative for me to believe that Apple should really fix the current problems before moving on? I don't believe it is. I believe it to be a difference in opinion, and a justified one at that, as I am a customer. If you don't like it, tough. No, I have not run Mavericks, and nowhere did I say that I am running Mavericks. As my post indicated, I haven't read too deeply into it. All I know is the new features that will be noticeable on the surface, and none of these are exciting.
Wow, they improved performance for my rMBP? You are right, I SHOULD be impressed! To heck with improving performance for Mountain Lion; I should PAY more money to have the performance expected of a $2500 machine. Yes, sign me up to pay more money so I don't have graphical lag!
(For the record, calling a user's comments "worthless" because they are of a different mindset than yours simply makes you look like an ignorant trollolol.)
