Embedded Master™  implements Microsoft's .NET Micro Framework . This allows users to run C# managed code right inside Embedded Master. Users will use Visual Studio to develop and debug programs.
Not only that, Embedded Master  is the first and only OEM device that implements .NET Micro Framework and adds FAT file system and USB host capabilities. Users can access files on SD cards or USB memory devices (thumb drive, USB hard drive...etc.) and also use many other USB devices such as, mice, keyboards, joystick, printers, Bluetooth dongles and many more.
Windows SideShow is also fully supported through USB or Bluetooth, and this is (next to the FAT support) the second big feature I will love. Not to connect the device with a USB cable to the PC.
