Grow a pair pessimists. Every new release has its teething problems on any software Apple or not. Apple did a fantastic job with Mavericks and if you are such whiney rats why do you keep Mavericks? Oh right because deep down you know it is great but you love to complain because you can never get enough pats or something. /woof
Wow, so dense. Without all these "whiney rats", Apple wouldn't know all the problems to fix them or how to make their software better for the users. That's what we call capitalism working. Get off your high horse and come back to reality. I'm not saying Mavericks is bad either, FYI, but their Mail app does suck and could use huge improvements. I'm sure some are coming that they had in mind themselves, and now maybe some from the users since they "whine" about it.
