Took mine back out and tried again... Used it for about an hour then grabbed the Pro, which I've been on since it was boxed up. I still no can do as the screen is noticeably dimmer and washed out on the Air...
I have to head down by the Apple Store tomorrow for an errand so back it will go then. Crashed it and reinstalling the OS now... Bummer as I really wanted to dig it.. touchID without the gimmicky TB on my Pro...
Oh well... It's a fine computer and those coming from the old Air will absolutely love it, I am sure!
