IMO Blu Ray's draconian DRM just plain sucks and not worth the better picture, it's just not that much better.
I'm amazed and very happy the way my DVDs from Netflix ripped and played using my AppleTV looks on my 67" HD TV so at this time I have no burning desire to get a Blu Ray player.
Anyway DVDs are already like so yesterday with everyone coming out with Movie Boxes.
First the AppleTV
Then the Amazon TiVo movie rental deal.
Then the Netflix box.
Now this movie box.

The only thing that sucks is each place requires their own box.
