So, on the one hand, I read this as a buzz-laden attempt to find the holy grail of programming. "Highly complex yet simple to use" is a very major challenge on its own. "Cross-platform non-resource-hogging simple native app" is another very major challenge. If you can build ANY app that meets those criteria and does it well, it's likely to succeed. Ignoring the idea of the app altogether, go tackle a problem in a domain you have familiarity with and kick its ass. Ignore existing competitors, as the above-referenced feature set will destroy them. As for the idea itself, what's different about this than something like "GoToMyPC"?
