Agreed. As has been well-chronicled by yours truly here and an alarming number of posts on the Apple support forums, this is the sloppiest release I've ever seen.

What I'd be interested in learning is if all these issues are update related, or native. 'Nudder words, would one have the same problems with a brand new Mac with Mavericks factory-installed (or installed on a totally clean drive), with all other apps then being freshly installed, as opposed to installing the update over a complete system and other user-installed software?

If even a factory install is buggy, then Apple is going to piss off and potentially chase away hordes of first-time Mac users.

Most disappointing.
