I am not an expert, therefore this is in laymans terms. My nephew has the PS3, and I have the S350. From my point of view the picture is noticeably better on the S350, and almost as importantly it is also an excellent upgrader of normal DVDs. My wife loves the Lord of the Rings stuff, and it is just brilliant on the S350, as are a lot of my other DVDs (just watched Blade Trinity DVD earlier today, and to be honest the picture is that close to blu-ray standard that I won't even bother getting the film on blu-ray).
