Googles DIY tool for Android

Google has released a Do-It-Yourself tool for Android whereby anyone can develop apps for Android. You dont really need Programming skills is what they claim. The video showcasing this tool portrayed a very simple app but I am not sure if this tool can help build complex apps. But I guess programming with a programmers mind set is any day good. Yes, tools are important but they can only help you so much. I am curious to see if a game changing app would come out of "App Inventor". Maybe Google just wants to get their app count competitive with Applez.
