27" iMac is bigger than any iMac before it. It's actually slightly thicker than 24" as well. Apple made it 27" so they could give some horsepower to the iMac. They could have made it 2cm thick and use ULV CPUs but who really wants something like that?
Screen permitting, displays are the only component of a desktop system that evolves by increases in size, in terms of actual screen real estate of course. Yes, and I do agree that the 27" is made specifically for more horsepower, and seems to be the sweet spot for the prosumer/working professional bridge. I was referring more to the 21.5" models as the consumer line with their low price points and integrated GPU in the base model.
Seems again like this is slightly treading into that fabled subject of the prophetic death of the Mac Pro in the near future, when Apple fully goes iMac for their desktop line. Without getting into that really, I would like to say that I think if the Mac Pro does indeed see it's demise, I could see Apple dividing the iMac line into an iMac and iMac Pro.
But to reiterate my stance, the linear evolution of base level iMacs have continued to shrink in size.
Even G4 Mac is able to run Mail and Safari but if you take a look at what Apple is currently offering, there are no G4 CPUs. Bill Gates said that home user will never need more than 640KB of RAM. He was wrong, totally wrong. Technology will develop and we will see faster CPUs and GPUs in all computers.
We
should see faster CPUs, but we didn't see that happen at all in the new Macbook Air. Indeed, that was a downright step backwards in terms of "raw numbers". Yet, the Air is proving to be quite a success so far, as I've seen on these forums and on the numerous Youtube videos and critical press reviews.
So, it seems it was a good idea to include flash drives as standard in the new Air.
Software is getting more demanding, that's why. Sure you can play SD video in G4 Mac but think about Blu-Ray rip, it won't work. And no, Blu-Ray nor 1080p is the point where everything ends, there will be newer, more demanding technologies. For instance Super Hi-Vision. It sounds impossible at the moment but so did Full HD in 2000. BTW, uncompressed Super Hi-Vision is around 3GB/s (24Gb/s). You need some serious horse power to play that.
What type of software you referring to? I'm just talking about Mail, Safari, iLife, iWork, and those types of consumer level apps. Not pro-apps. Not serious audio or video editing apps such as FCP or Logic Studio. And as proven, consumer level apps seem to be working beautifully on the new Macbook Air's extremely modest 1.4 C2D processor so far. Also, do you know how many average consumers are even ripping blu-ray media at 1080p?
And speaking of blu-ray, I do agree with you. It obviously doesn't stop there, and I made no assumptions that it would, but no way are we going to see anything above blu-ray anytime soon in the consumer market. Penetration for that media is still underway and is still being steadily nurtured by Studio companies. To introduce yet another medium to consumers is just asking for a mess.
And look at downloadable media. Apple is not even on board with 1080p. The new Apple TV proves their stance with only 720p support. Also, ISP infrastructures with their bandwidth caps and limited availability of super high speed internet will get us nowhere for the time being. No, we're a ways off from anything beyond 1080p right now. As such, I doubt Apple is worrying at all about Super Hi-Vision in the near future. Apple will have adequate amount of time to shrink their products even further while staying current with practical consumer needs. And that's really the key phrase I'm trying so much to stress here: practical consumer needs.
Web browsing is starting to be pain in your ass with older computers as their CPU isn't juicy enough to playback Flash fine.

Sure things will get smaller (there was no MBA in early 2000s for example) but the logic that "current computers are already fine" is not valid. People would sill be using their G3 Macs if they really fulfilled their needs. But looks like they don't.
It's just my opinion but I can't see ultra-thin iMacs anytime soon. Apple has just made them bigger all the time
No, I don't agree technology will stop and that we should be content with that, but Apple is proving to find just the right sweet spot of technology vs. (again) practical consumer needs. Can the average consumer live with a much much slower processor to run their basic apps? Thanks to the first time ever of flash drives on a Mac, I think consumers so far are agreeing so with the new Air. You could say the flash drives on the Air is probably the primary important new addition that offsets the drop in processor clock speed, which allows Apple to reduce size. It's just a different approach, and a creative one at that, of designing a thinner computer.
The obvious logical choice to making the iMac thinner is to simply follow the formula they had with the Air. Why wouldn't you think removing the optical drive for one, and going completely flash drive on the 21.5" models would be feasible? You can see Apple's direction with optical media. They changed the icon on iTunes and was even stated by Jobs at the All Things Digital interview with Walt Mossberg that they "see it headed in that direction", and have time and time again disagreed with blu-ray support. Anyone wanting to use optical media can just go for the USB superdrive solution. This probably actually makes Apple more money anyway so I see it highly likely that it may happen one day.
Again, not including the 27", the current base line 21.5" is thinner than the last model, which is also thinner than the white iMac. So in terms of baseline machines, there's a natural and steady progression of size decrease.
So I'm curious as to why you don't think at least those two approaches mentioned above (optical drive gone, all flash drive) would be practically feasible one day for the iMac? I know you say you don't see it, but judging from history and advancements in their other product lines, it is clear as daylight to me they will push headstrong into even smaller form factors in the future.
