I mean I can understand running Linux on a Raspberry Pi, essentially it gives you a full developmental platform where you have all the tools to directly develop and debug your software. In the area where the Raspberry Pi and platforms like the Arduino overlap, that's the big advantage of the Raspberry Pi...
But here we have a "headless" Windows, a Windows without windows. You cannot even run Visualstudio or VisualBasic on it. Just like on an Arduino you need to develop on a PC and then "flash" it to your Rasperry Pi.
I could understand if they would have simply ported a slimmed down Version of Windows to it. Something like a Windows 2000, perhaps with x86 emulation for non-native software. That would have had some use.
