Both HD-DVD and Blu-Ray have lens assembly that support Blue and Red laser diodes. I think that the HD-DVD assembly is smaller and more efficient though because of the close similarity with DVD.

No really? I didn't think HD DVD had the blue laser.
The HD-DVD camp was originally dedicated to using red lasers to save costs but they finally realized you can't have a decent HD format using red lasers even with MPEG4 compression. They switched to blue lasers a while ago. Both HD-DVD and Blu-Ray will require blue and red lasers in order to be backwards compatible with DVDs and CDs. The only real difference between HD-DVD and Blu-Ray discs is how close the pits (information) are to the surface. Blu-Ray has them very close to the surface so the pits can be made closer together which results in more capacity and faster transfer speeds.
1984, that was an interesting link. However, what I found most revealing was that the first three responses to the article in the message board was "so what, who cares, why upgrade". Given the very large base of DVD players and personal collections out there now, there's a very real possibility that some companies are going to loose very big bucks if consumers sit this one out, which they just might.

I mean you could replace DVD/VHS with almost anything. I just don't get this mentality, and it creeps up everytime something new is on the horizon.
Cars replace horse drawn carriages? Why did CDs replace tapes? DVDs replace video tapes? Computers replace typewriters? PS2 replace PS1?
The great thing is that both formats are backwards compatible. Meaning that your next DVD player purchase could be a next-gen player, and there is NO loss to you. Your existing collection will work, and all movies you purchase in the future will work. This will go smoother than the transition from VHS to DVD, based on the fact that next-gen DVD is backwards compatible, where DVD to VHS was not.
Clutter control. Certainly once the price goes down the additional time you can fit on a disc at SD will be a major selling point.
And don't forget quality for those of us that have HDTV's. I have a 65" HD projection TV, and because it's projection TV the picture will never be as clear as a plasma, tube, or LCD HDTV, but I still can definitely get over 50% + increase quality in my picture over regular TV's when I'm watching an HD signal. And I can seriously see the difference between Super-bit DVD's, and regular ones. So the most obvious point of HD-DVD's I think is because the the whole TV industry is going to only be making HDTV within the next few years, and having the corresponding components to match is a must.
You bring up a good point. My mother purchased a Sony 65" HD compatible TV and regular broadcasts looked like garbage, DVDs looked better and HD Sports looked Greeeeeeeeeeeeeeat. I don't think people will "get" HD until they bring home that 50+ inch screen and start noticing why Superbit DVDs look better.
Hell I watched a DVD recently that avg about 4.5Mbps and looked just fine on a 27". It would have looked crappy on a 65" though. Size does matter.

DVD is more convenient than VHS because of menus, chapters, no rewinding, etc. The next generation formats don't have any such huge advantage.
