I am looking for a TV for 9' x 12' room. Need help deciding between HDTV 36" like the Sony XBR versus a smaller RPTV like the 40" Toshiba or 46" Mits which are comparably priced. Is the direct-view picture that much better to make up for its smaller size? Either one better for setting up a HT system? Would watch cable and DVDs. Which would you choose?
