With HD-DVD and Blu Ray, we have surpassed those limits - encoding artefacts are all but eradicated on a good transfer, colour gamut and depth are wider and broader respectively, giving more realistic hues and tones and able to paint the original celluloid with a much more accurate digital representation.
1080 lines of course have their benefits for users of extremely large screen sizes. One of the problems with marketing Blu Ray is, how do you persuade the public of its appeal? In the transition from VHS to DVD, the benefits were immediately apparent and both visibile and attainable for all age groups. The conundrum with Blu Ray is how do you create a similar distinction? It is hard to market the things I have mentioned - try explaining to your average punter the inherent superiority of VC1 over MPEG-2, or of the benefits of improved colour depth and a wider gamut.
1080 lines has been pushed to the fore because it's easy to explain and - with a big enough screen - it's easy to perceive. In the UK there is an inertia for manufacturers to include native 1080p panels on screens as small as 32" for people who use it as a casual lounge room television - a clear cut case of people falling for the marketing guff. In my opinion, a display should be chosen for its colour accuracy, its black depth and whether it suits your logistical needs (price, features, size, aesthetics etc).
Resolution is a nice caveat to flaunt on the shop floor but the only thing we enthusiasts should deduce from its marketing success is that people are increasingly looking toward their home entertainment systems to blur the distinction between reality and fantasy - a suspension of disbelief, which NTSC and PAL did perfectly well, is no longer adequate.
The implications of this are of course for psychologists to speculate upon rather than engineers like myself, but it's something worth considering never the less

That is a very good point. With Blu-ray, there are far fewer artifacts and other errors and limitations than with DVD, despite the resolution. That is a great tool, but not many people would buy something for those reasons alone.
Interactive menus and internet connectivity are nice but again, nothing worth the investment in and of itself. I think it is really the combination of HD resolution, higher quality audio and video, and advanced features that make Blu-ray such an appeal. Perhaps resolution is over-rated, perhaps it is over-hyped, but it is a strong selling point nonetheless.
I know many people that "like" distorted images, cropped movies, and worse (often out of ignorance or laziness). For them, color depth, 24p, and encodes mean nothing. Convincing them to buy Blu-ray is very hard, since they are so happy with "full screen" (shudder) DVDs and such.
As more people buy HDTVs, more people will find out about Blu-ray. We enthusiasts are the only ones that are really concerned with all the technical and subtle nuances of Blu-ray movies. We have to lead the charge into Blu-ray, by setting the standards. Eventually, the rest will buy in as well, not knowing all the advances it has made, the better quality it offers. Some day, they will look back at DVD and say "I can't believe we ever watched that!"
As for an explanation why DVD isn't good enough for us anymore, to me it is simply that we are always striving for something closer to reality than ever before. As DVDs had clearly better quality, it was the obvious choice, and if there were no other options, it would still be that way. But as technology around us gets better, we see advances in everything from iPods and cellphones, to computers and electronic books. As they advance, we expect other things to as well. it is only natural that, after seeing an ipod with a 201 ppi screen, we want to see a TV with the same kind of resolution.
