im an Xbox fan but the 360 Slim is pretty shit tbh. The only difference is it looks better and has some good features like the built in wi-fi. BUT they have not solved the overheating problems or the RRoD red light problems. So overall its pretty pointless if like me you wouldn't use the new features anyway.
for me the new xbox looks just like sex
and I buy them to me not only so the new features just sound sick and the console is not even loud like the old one .
and cookie they do an new methode 2 put the RRoD problem down...
just google it and you will see
