I had only a PS3 player, although I'm also contemplating on getting a Blu-ray dvd drive for my PC Win7.
I wanted to get the BR version, having it as my first Blu-ray disc. But then I thought that I always ripped my dvds, especially the concert/lives and then convert/upload to my ipod/iPad/Smartphone. My software doesn't do Blu-ray, I don't think, so I'm getting the DVD first. it's also cheaper....
who knows, I may get the BR version when I get the money and if it's big step up. I mean I know BR is HD, better picture vs DVD, but how much better? I still don't know.
