Glad to see I am so popular. I see that I did come off a bit strong, but generally still feel the same about what I said. To clarify a few things:
Up scaling DVD players are not a bad idea they are an improvement, what I meant was they are not comparable to blu ray. Sorry to anyone who felt I was calling them an idiot.
My issue with purchasing a drive, than a disc, and still having to purchase software to view blu ray is just this, the SAME disc, in a standalone player (sometimes with the EXACT same optical drive hardware), will give you the same movie, with no extra software cost. Yes pc drives cost less than standalone typically, but it’s not like the rest of the computer was free. Hopefully Vista SP2 will help this some with its native blu ray support (to write at least – it’s a start). Notice that no special codecs or software are needed to view DVD’s in windows right now.
And don’t get me wrong, I am cheap when it’s appropriate, even when buying expensive things one can research it and make sure they get the best possible price. I still buy about 90% DVD and 10% blu ray, because not every movie needs (or benefits from) blu ray, as has been mentioned by others already.
A common (misconception?) argument that I have heard a few times, that really is kind of annoying, is that people say "I don’t want to have to replace all my dvd's to switch to blu ray." To which, I simply reply, "ok then, don't." Blu Ray players all can play your current DVD's, they are not instantly obsolete when you bring a blu ray player into your home. In order to adopt blu ray, all one has to do is purchase a player (which is a onetime cost, and although higher than DVD, like DVD is quickly eclipsed by the actual cost of the movies being purchased so this argument is not that strong - at least in my mind) and buy some blu ray movies. I would actually recommend to anyone considering the new technology to do what I do, and that is NOT buy 100% of movies from now on in blu ray, just exercise some thought on what movies would be worth the extra cost (because I will recognize that blu ray movies are still on average about $25 - but there are always deals out for the motivated).
Hope that has cleared some things up, not trying to offend anyone or make any enemies here.
