So we all know that the PHD8 is the HD screen and the PWD8 is the SD one. And the general concensus is that the PWD8 will still produce a good picture through HDMI when HD Sky arrives. However how much better is the PHD over the PWD? Obviously when placed side by side the PHD will shine. But in a living room will you notice the difference on a day to day basis? What are the actual screen resolution differences and how does that equate to the viewable HD picture? What I am getting at is. Is the PHD worth the extra money now or is it better to go down the PWD route and then get a next gen screen, ie the soon to be released £5000 pioneer, when they become cheaper?
