Just got a 40d5000 and also own a 40c5000; 40d is lighter and build quality is slightly lower than 40c; but picture quality is much better and has added support for controlling it via phone (android phone app needed is samsung remote) which I'm using and working fine; Inputs have been removed like there is no separate inputs for av in and component in and they have been clubbed into 1 by a special cable i.e. only only either one can be used at a time, though I'm using only hdmi which it has 4; so overall I feel it is a better package than 40c due to the enhanced clarity specially of hd and full hd content.
