I can only comment on blue-ray. Definitely not worth it right now. As far as I know, it's still very cumbersome to watch a blue-ray. You must rip it, which looks very difficult in general, before you can watch it. So, if your friend brings over a blueray movie, you're gonna have to wait to watch it. Plus, I think that not all BDs are rippable. So, probably want to wait on that till we get live read functionality.
