I've been on the non-touch 13" for about a week now and I'm really happy with it. I moved over from a 2012 11" MBA. The form factor of the 13" is great for grabbing 30 minutes here and there during travel to do some work.
Battery life is good, and 16GB is a big step up from the 8GB I had on the MBA. I've been running a decent-sized system in minikube with no problems.
The only issue I still seem to have is that Hangouts absolutely obliterates the battery. A one-hour call took battery life from 9:45 to 1:15!
