Hands on with Mavericks, thoughts?

Just installed Mavericks on my late 2012 27' iMac and my early 2008 Macbook Pro..and so far this thing is quick..for the iMac that it, much snappier that ML. My Macbook will show its age regardless i think - the 2:30 boot up still lingers..

One thing that stands out though is how brutal top sites looks like in safari on the big screen..everything is stretched and distorted..same for anyone else??

Other than that its just fine tuned things which is nice, maps and ibooks are meh, but overall I'm a happy guy..and free is always nice!
