I currently have a 2012 MBA with 4GB RAM and a 1.8 GHz Intel Core i5. Generally it's ok but I've noticed 3 things: (i) battery life is down to under an hour, (ii) serious fan issues and slow down when I have multiple apps and Chrome tabs open, (iii) it can't stream some 1080p video at full screen. I've absolutely loved owning this machine and adore the keyboard, trackpad and Mac OSX. I'm wondering whether it's worth buying a new MBA with 8GB RAM and perhaps the i7 processor or should I get the 2015 MBP while I still can? I don't like the keyboard/lack of ports in the Macbook and the 2016 MBP.
