I know that Macbook 12 inch was created for battery life and it's lightness instead of performance, but I am really curious about it's performance for development purposes.
Did anyone actually test it on the real device? If so, what do you think? If not, what's your opinion anyways?
While XCode is compiling, will I be able to open safari without seeing "the rainbow"? Slow compilation is not a problem, but I want to know if it hogs the whole OS or not.
