I have some son Raspory Pis B, this Raspberry Pi 2 I've actually bought in the living room as a replacement for my media player. He is not yet really to use, because I have not found a stable XBMC version of the Pi 2 for the intended use. Instead, he is at the moment as an experimental computer in my office. The four cores and the extended memory do very well noticeable. Unfortunately USB is lame as well as to the previous PIs.
