Perhaps sometimes things aren't too good to be true?
Adobe has been working on an awesome code editor called Brackets
It is a FREE and OPEN SOURCE code editor (can be embedded into whatever you want).
More Information here
Anyhow, I see people eyeballing it who use Sublime Text
There is also Light Table
The coolest part about Brackets it that you can program your own extensions. It supports all sorts of languages.
I myself, wouldn't have expected as much from Adobe, so at first glance, I might have ignored it, but I stumbled across it.
The first plugin I downloaded was one that runs the current loaded python script (I have Python for Mac installed, with the wxPython module, that loads using the Python Launcher). And it works nicely!
A solid program indeed. I was just wondering what others think about it.
Update: While watching a youtube tutorial, I heard about atom:
It is made by Github.
