What still gets me: HTML/CSS/JS honestly just sucks for building complex apps. We have shoehorned tools that were meant for simple document display into doing our bidding, but at what cost? Hours and hours of developer agony. It doesn't need to be this hard. I like looking at one file written in one language to see both the look and behavior of an app. There has just been too much mental overhead. I like the way things are going and this framework is step forward.
