OSX Mavericks

It's about time... OSX Mavericks addresses some pretty serious issues I've had with my Mac since day one.  Why these things took so long to be included in OSX is beyond me.  The two new features I'm interested in are the improved handling of dual monitors and the battery graphing feature in Activity Monitor.  

The ability to hide the unnecessary GUI clutter with full screen app is pretty nifty indeed, but I never used it. In the past two versions of OSX, full screening an app with dual monitors caused the app to take over one monitor (expected) and the OS to render a worthless gray texture on the other (WTF).  Full screening an app now leaves the other monitor free to display other programs, the reason why I bought the second monitor to begin with.  Also, the menu bar is now displayed on both monitors instead of only the primary monitor. 

The second irksome issue Apple addressed was that of battery time tracking.  I can see how long my phone has been on battery, so why couldn't I do this on my Mac?   Now Activity Monitor includes a graph of the machine's battery charge over time, so I can see how long my battery has actually been running my machine, instead of just guessing. This pleases me in a very nerdy control freak sort of way. I'm sure there are others out there that will appreciate this new feature.  

There's not a whole lot to lose by upgrading to Mavericks; hell, it's free, and it runs on machines made back in 2007.  It's nice to get a free upgrade every once in a while, especially after having to deal with Mountain Lion for the last year.
