I don't really plan on using win-IoT core. Even though I have a background in .NET I don't see it being compelling enough. especially where the dragon board is new and the IO is 1.8v. which most of my spi/i2c stuff is 3.3v that i have now will need to have a logic level converter to bring it down from 3.3 to the 1.8v. I played with the linaro ubuntu but i am noticing networking issues where i can't ping my other devices. Might go back to android until the linux scene gets better for this device.
So far I really like it, it's a bit more nimble than the raspberry pi 2 i own. which before was my fastest device. also when is this getting marshmellow (android 6.0)?
