I have a XU4 and the only reason I got it was for the 2gb of ram. I don&#x27;t need 8 cores and I certainly didn&#x27;t need a fan.<p>I&#x27;ll be getting a C2.<p>Does anyone know if the USB ports are fully powered on the C2? As I can power a USB HDD from the USB port on the  XU4 (this is a big thing for me as it saves another power source).
