Yeah, I didn't see anything I'm interested in as a "power-user".
OSX lately has decided to hide a ton of features out of the box that require changing values in Terminal before being useful. A quick list I know of: - Hiding full paths in Finder - Launchpad can't actually delete things. - Library is hidden
Other weird default settings: - Scroll with trackpad is inverted
It also doesn't have Ubuntu's nice window snapping or Windows' snap to sides feature, which is a big time saver.
Finally, I don't feel like "port iOS features to OSX" has been a win for Apple. It just seems to confuse people by adding more crap to the OS.
