Yeah, installing is not easy but can be done, even a computer noob like me could do it (after some problems). Now I installed a nice/clean theme, I am really loving it. It might not be the highest end sound around but it provides very good capacity + battery life. It plays all my files, it has easy UI and user experience. Also it has a line out, so I can connect an amp later on. The size is nice too.
Mine didn't even crash once after I Rb'd it. Seems quite stable.
