Microsoft has recently announced that Windows 10 will be available on the new Raspberry Pi 2 released just this month. The Raspberry Pi 2 is still the same $35 price and small form factor as its predecessors, but now boasts a quad-core ARM Cortex A7 CPU @ 900 MHz and 1 GB of RAM! Windows 10 will be free for members of the Windows Developer Program for IoT. I'm glad to see Microsoft become involved with Raspberry Pi development. It will be interesting to see how this turns out. https://dev.windows.com/en-us/featured/raspberrypi2support
