From Intel website:
If you've used appMobi's HTML5 development tools in the past, then you're already familiar with our new tools. We're introducing this set of cross-platform HTML5 tools as Intel's HTML5 Development Environment to help you more easily develop great HTML5 apps for all of your target devices.
I checked out the Intel "HTML5 Dev Platform" and found it woefully lacking. It was, at best, an alpha product as I found it challenging to even get running. I'm not really sure what Intel is doing with this product when much better, infinitely more mature products already exist. I mean, Netbeans 7.3 offers far more functionality and the same "free" price tag. I was frankly shocked to see something so amateur come from Intel.
