Yes, the jump from DVD to 720 is a noticeable difference.
the transition from PAL DVD to 720p isn't all that obvious.
unless your display doesn't fill up at least 30° of your field of view, telling apart PAL DVDs and 720p materials can be tough. especilly because 720p is only used in broadcasting and is hugely bandwith bound.
as for NTSC DVD vs 720p or PAL DVD vs. 1080i/p there is definitly improvement.

wow i just watched those comparison images, and i feel shocked the difference would be that huge :o i smell something fishy here.
I bet thats quite extreme comparison, thats awfully blurry for even a dvd. ;o

there's no color that dvd movies can't represent. so if there is any difference between the color palette between the two it's not because of some flaw in the dvd format, but the studio just decided to encode them with different colors. in those shots the bluray movies look green... but the dvd ones could have looked green too if that was how they encoded it.
the resolution is a bit better... but that link exaggerates the difference. you can just look at the method the guy used "I used Photoshop to bicubically resample the DVD source images from 852x480 to match the 1920x1080 of the HD images.". so... basically he took a low resolution image, made it a lot bigger in photoshop, then shrank it back down for his webpage. you're going to lose detail if you do that. so it makes the dvd look a lot worse in comparison to bluray.

Blue Ray has a superb quality. We have a home cinema system with DVD player and normally only watch DVD. But my notebook has a blue ray drive (and a hdmi adapter) so I tested blue ray. The quality is great you really see every detail (I watches I am Legend). Before I tested it I did not know how great the difference is.

Are you a salesman? I'm just waiting for more stuff is on blue ray, specifically remakes of good stuff.

it is true that a dvd can represent any colour, what it cant do is represent any colour range. there are limits to the amount of data that can be used to describe changes in colour, both over a frame and over time. these limits are higher with bluray. both disc formats are encoded, it is not a simple matter of 'X pixel is Y colour'.

on a lap top screen?
no you won't see a difference.
edit: plus blu rays are more expensive than dvds
you can definitely see the difference. my laptop is hd and the difference is immediately evident whenever i watch something in hd.
it is worth it if you plan on using the blu ray capability often. if not, dont waste your money.

with a blue ray player would it still be easy to dl/watch blue ray stuff in terms of is the format widespread and available and is the file size huge?
"assuming" im only dling legal stuff.

Blu-ray is dead, don't get it.

No they are both dead they spent too much time in the format war while technology caught up. People will stick to DVDs esp dual layer for spinning media / digital downloads / solid state media unless they start giving out blu-ray players for free.

no way. people who argue that streaming will play a major role in the distribution of movies in the future are right, however connections aren't fast enough to stream bluray quality and won't be for another couple of years. you can already put 32 layers (iirc) on one disc. how are you going to stream tens of gigabytes over the net? korea != rest of the world

IMO not worth it watching bluray on a small screen such as a laptop.
On a big screen such as 50", it will be very noticable and well worth it.

Bluray encodes video differently allowing for a larger color range, just compare any dvd with any bluray movie, you will always see difference in color and contrast even if they were released at the same time.
Making it bigger then shrinking it down wouldn't lose any detail. But shrinking down the 1080 bluray shot does make it lose a considerable amount of detail. So even though those shots aren't fair, you can still be sure that bluray is even better than the comparisons make it out to be.
Second of all read what he actually wrote. He resized each image (bluray and dvd) ONCE and only once. What you see on the page is 1080 resized down to DVD. But when you click on the image what you see is DVD resized to 1080. He didn't resize the DVD up then back down to its original size, that's just fucking stupid.
Here:
http://www.cornbread.org/FOTRCompare/FOTR_Compare1_DVD.html
Now click on it once its loaded to see HD and when you have both fully loaded you can keep clicking to switch between the two and see the clear differences. You'll probably notice that in addition to looking a hell of a lot better that you can read a hell of a lot more on that map also.

You must be slow... Blu-ray won becuase it allowed everyone to creative blu-ray not just monopolized which is why it won alot more stuff can be put out there for cheaper. If you don't remember jack shit back in like 2001 or w.e when dvd players cost 400 bucks guess what gave that 4 years and you can get them for 100 now you can get one for 25 bucks. You can get really nice quality blu-ray players for about 150 give it a year or two and that be down to 100

Right now, every laptop manufacturer is offering blu ray players as a upgrade for only $150. The reason that blu ray players are so expensive now is because it takes a lot of cpu/gpu power to decode a 1080p h264 file. As technology progresses, the prices will only go down.
I don't think streaming will come close to blu ray for the next 5 years. The best HD streaming site is youtube right now. But you can't watch copyrighted material on youtube. Youtube HD is 720p at 2000 kb/s. The resolution and bitrate is not even close to Blu ray. It seems like google is the only company that could afford the bandwidth to stream in HD. I remember Stage6 closed down last year because bandwidth costs were too high.

I have a 1080p 50" plasma and DVDs through an upconverting player look awesome. They're not QUITE as sharp as Blu Ray but it's a nominal difference. The added cost of Blu Ray and the fact they're not nearly as convenient to rent as DVDs also discourages me from buying them.
I think streaming video / video on demand / downloadable video / yada yada is going to make Blu Ray obsolete before it ever really gets big.
As for the OP... an extra $150 for Blu Ray and 1080p is only worth if if you're willing to pay $30 for movies instead of $20, and if you're willing to choose from a limited selection of movies, and if you're willing to rent from the few places that have Blu Ray.

And yeah those comparison pics are 100% accurate... but it's a lot of personal prefence here. Some people just don't care that much. I'm all for extreme quality but Blu Ray doesn't deliver in a satisfying way... too expensive, too limited in selection, etc.

Yeah, remember when the PS3 came out and people were buying it instead of bluray players because it was cheaper? Its changed now but prices drop quick for technology that's in demand and it drops naturally over time due to technological advancements. There may not be as big of a catalog of bluray movies but the same went with VHS -> DVD and people still bought dvd's left and right.
EDIT: Besides, complaining about 'not enough selection' is stupid. Most bluray players can play DVD or Bluray and a lot of them upconvert DVD's to 720 or 1080.

You will notice a difference between blu-ray and dvd, even on your 16" laptop monitor. Your monitor is capable of 768 lines of resolution vertically. DVD resolution is 480 pixels. You won't see the entire detail possible on your monitor, but it will be better than DVD. That's like 60% more resolution. And as other's mentioned, there is more than just better resolution to make the picture better.
