I really don't think it is. As interesting as the Compute Card is, it's nothing more than a continuation of recent trends. It's another compute stick that's trying to chase the "modular" fad everyone has been hoping for the last few years. Yes, it might be a big thing, but it's not "the next big thing." I'm sure, if thermal management and price points are correct, that the Compute Card will be a truly useful and innovative device. It reduces the cost and risk of moving your entire PC around. However, it's not what Microsoft is looking for. Ten years from now, not everyone is going to be carrying one of these instead of a smartphone.
