I updated shortly after it hit the CDN. I'm not sure I like it, to be honest. I don't dislike it either. Apple is trying something new, and it is neither better nor worse than what they started with, and I'm not going to slam them for finally doing that.<p>I'm actually looking forward to a more refined version of this in OSX 10.11.<p>That said, everything seems no faster nor slower, and battery life seems to be the same.<p>The improvements I do like is the About Mac dialog is a lot more useful than it was, Spotlight is a lot better than it was (I use Spotlight as an app launcher for anything I don't keep pinned to the dock), and the font rendering engine seems to improved (and the change in UI fonts really shows that off; other than that, thin fonts stay thin instead of suffering from the usual OSX fatness).<p>The dark menu bar/dock theme is a neat idea, but I don't really care for the execution. I'd rather it switch back and forth depending on the background I have (and I have backgrounds on rotation).<p>I use Chrome, iTerm2, Homebrew, Skype, Office365, Evernote, Todoist, and not much else, and everything seems to be working fine.<p>I still don't like the multi-monitor experience on OSX. I want "Displays have separate Spaces" off, but not have full screen apps take up all monitors, especially when they can't use them.
