I watch blu-ray on a 46" 1080p Panny plasma and on a 720p 32" Samsung LCD. Getting a BD player for the later was definitely worth the upgrade to get maximum benefit from the TV. It actually accepts the 1080p signal from the BD player, as many of the newer 720p TVs do now. And prior to getting the 1080p plasma in Nov. 08, I watched blu-rays on a 34" 1080i CRT TV from my PS3 for over a year ... loving every minute of it.
