Going to make a slight retraction here. In the first post, I said I kind of like the look of Mavericks. As it turns out, I've been having quite a bit of trouble with the new OS.
I'm not sure how do you *really* compare, but OSX9 it seems to run notably slower than 10.6.8.
I've got a bug that's driving me crazy, which Apple can't seem to fix, despite some serious time in Apple chat. From looking on Google, I suspect the bug is a rare one...but I've got it.
In trying to get my bug fixed, I've also spent a lot of time on the OSX community forums, and a lot of people seem to be having trouble with compatibility issues. When I signed on Thursday, there were over 5,000 conversations going, and this was only two days after it was released.
If I were to do it again, I might wait a while before upgrading.
