(Full disclosure: I&#x27;m the other founder of Floobits.)<p>I&#x27;m pretty excited about what can be built with Atom. Since it&#x27;s based on Chromium, you&#x27;ve got access to WebRTC for P2P stuff, getUserMedia() for camera&#x2F;mic, HTML5 audio APIs, canvas for visualizations... there are so many building blocks that aren&#x27;t available in any other editor.<p>Granted, Atom&#x27;s browser roots do slow it down. But it&#x27;s getting better. Even on my 1.1GHz MacBook, the only significant performance issue I have is startup time. If that&#x27;s fixed, I&#x27;ll probably switch over completely from Sublime Text.
