You've misinterpreted my point. Blinking LEDs is the Hello World of embedded systems. But if I have to develop all of the software myself that I want to run on the Pi, I'd rather just use Linux. The only benefit I see about having Windows running on the Pi, is so actual Windows applications can be downloaded and run on it. If that functionality exists, there should be a demo where you boot up the Pi, access the Windows store, and download/run a real application.
