I am of mixed feelings towards Blu-Ray. For one thing I really don't see a big differnce between Blu-Ray and DVD's watched on a half-decent TV set. Yes I know there are some bells and whistles, but really when it comes to film -- and I mean real film, not digital masquerading as film -- I see very little difference. Digital media and video? Yes, usually.
As most of the films and TV shows I buy and watch really don't upgrade well, I am in no hurry to make the switch (that and the fact I have more than 1,300 DVDs and am in no mood to switch all of them over, assuming 1/10th of them are ever actually issued to Blu-Ray.
(All this said I'm very interested to see how The Prisoner turns out on Blu-Ray, seeing as it wasn't even shot on 32mm).
Fortunately, Blu-Ray players are backwards compatible. That's a big brownie point in their favor. But I had opportunity recently to "test drive" my brother's Blu Ray and his big 40-some-odd-inch widescreen plasma. I tried watching some of my older shows and found the picture quality to be unacceptable. I don't expect the same level of picture quality as I might with, say, the new Star Trek film. I am realistic. But I do at least expect it to be on par with how my DVD player plays it on my old 24-inch TV. If it makes it look worse, I really have little incentive to upgrade. Especially if, as I say, the majority of the DVDs in my collection predate the year 2000.
What's annoying me is this attutude some people have of "put up and shut up." I even had one guy say "just throw them out". Frell him!*
Anyway, standard DVD isn't going away anytime soon. BBC Video just announced they're releasing Doctor Who DVDs until at least the end of 2013. That says to me not every company is trying to forcefeed Blu-Ray ... and the fact they're committing to another 4 years of the format -- and no studio to my knowledge has made any announcement that they're retiring DVD anytime soon -- leads me to believe I'm not the only one who is being blown away by Blu-Ray (well, that and the fact a growing number of people just don't give a damn and are downloading everything to watch a few times and then delete).
All that said, if you're just starting out, if you've never bought DVDs or Blu-Rays before or are just getting your first player, then of course go with the Blu-Ray. But I do find your mileage will vary as to whether you're blown away by it or not.

* Sorry, I'm a bit hyped about the upcoming release of the complete Farscape on DVD (no Blu-Ray in sight, btw).
