I am very happy with my 11" MBA. Except I could use a larger screen and a higher screen resolution.
I wonder if the 12" is noticeable slower than the (1.7GHz i7) 11" MBA.
Shorter battery life vs. significantly reduced computing power (due to reduced heat dissipation). Personally, for the development use case, I'll take the reduced battery life; I can mitigate that problem with a power cable.

From what I've read it is about the same speed as a last gen macbook air.
In short bursts, but for any prolonged computing, the air will pull ahead due to the active cooling.
I use an air as a development machine, and it works great.
Well, to be fair, any prolonged, heavy computing will also kill the Air's battery. And the fan sounds like a freaking plane taking off.
