That may be so, but when I run something with Node.js in my browser, then I may have to close other things. So, wherever it runs, it really uses too much resources, and therefore I find it as a bad idea from the consumer perspective. It shouldn't be so, that somebody else, should dictate the content of your browser.
Node.js is something that runs on server ONLY. It's 100% like PHP but with JS instead. Your browser never sees nor executes Node.js code. It only operates on text a Node.js server produces.
The short definition would be: "node.js is something that eats up my browsers latency", something along those lines, and as far as I am concerned, that is everything I have to know about it. Node.js is a no stop for me.
