Well, i bought the 2013 11' i5/8GB/512SSD and it arrived on 28th June and it's running very fast and cool (except the Netflix Hd video where it feels little more than warm). I am still testing the battery life to figure out if it juices out to give me 9 hours or not. Issue: Whenever the air wakes-up from sleep, it takes more than 15-20 seconds to connect back to wi-fi (i dont have any 802.11ac), so may be its an over expectation from my side, but my regular 2012 aug mac pro connects instantaneously whenever it wakes up from sleep as i open the lid.... Also, the air does not disconnect once it's connected to the wi-fi. So it is not like the other wifi issue that others have reported where there is an intermittent connectivity. Thoughts anyone...?
