"Raspberry Pi and Windows 10 IoT Core: A Huge Letdown"
Hmmm. Basically the article says that it is indeed Windows 10 IoT Core, which does what Win10IoTcore is supposed to do, and is a platform for running applications.
Still, the author has a point. When Microsoft first announced "Windows
10" for the Pi2, several technical news sites tried vainly to contact Microsoft for more details, and most initially guessed that it would be like Windows RT, which we now know it isn't.As the article says, Win10IoTcore is suited for embedded system vendors replacing WinCE systems, and is of less interest to hobbyists.
