No he's not. Merom is not bad at all, and it is used in the iMac for cool and silent operation.
First, the G5 was hotter than Conroe, and the rev. C G5 imac was quiet and cool. Second, there are nvidea cards that are both cooler and faster than the x1600.
Quiet to some is not quiet to others. The WHOLE iMac 17" with Core Duo running 2 instances of cpu burn sucks 63W from an electrical socket. What this means, is that with the current parts the 17" iMac including display and all uses less power then the Conroe on it's own.
Conroe is a desktop part, and uses desktop chipsets (motherboards), ram, videocards. All of these will use more power then the equivalent mobile part. The end result would be a machine that emmited atleast double the heat compared to what it does now, and it would not be a trivial task to cool it down silently (considering the thin case).
I fully agree on the videocard though, I don't understand wtf they where thinking not upgrading the x1600 to even a basic 7300...
Third, the iMac is not a notebook on a stand.
It's about the thickness of alot of desktop replacement notebooks.
Again, I'll point you to the imac G5. The G5 could never go in a laptop
Ofcourse it could, I've seen 3ghz P4's in notebooks. The matter here is ofcourse Apples standards. They have a vision on what a notebook should be like, and that includes portability, long batterylife and silent operation. They achieved that with the G4, and now with Yonah / Merom. The G5 would have performed alot better then a G4 in notebooks, but they did'nt use it because performance is just one (important) part of the equation that results in user experience.
Similarly now, they have chosen to go with Merom... And why do you think they chose that way? Surely they have access to Conroes, and I'm ready to bet they have actually tested them in an iMac. I have built silent computers, and even with a 120mm fan on a large copper heatsink the differance between cooling a 35W processor and a 65W processor is huge. Having to use other hotter components would just make matters worse.
(hence this whole intel switch) but it was in the iMac, and quite successfully too, as evidenced by the quiet and cool performance of the rev. C G5 iMacs. The iMac also has a full sized hard drive. The iMac is a desktop, capable of taking full advantage of components that cannot fit in laptops (or minis).
When Apple was using G5's in the iMac, what speed where they at? What speed models where they using in the PowerMac at the time? What videocard did the iMac have? Is it possible they actually (like now) opted for using a slower processor and videocard to keep the heat levels down?
Finally, the gap between the Mac Pro and the iMac is absurd. There are loads of people who need something between a low-clock merom with last year's mid-range graphics card and a quad-core xeon workstation.
I agree, I just don't think the iMac is the correct form factor. As mentioned, people have differant perceptions on silence. The fact that the Intel 17" iMac was mentioned as the most silent "out of the box" computer silentpcreview.com has tested, tells me that Apple (like me) considers silence to be one essential feature for computers (when possible).
With a Conroe the iMac could be silent during idle, or extremly light operations (it has fairly good powersaving features), but as soon as you would create a load it would start to scream (due to the small fans in the imac)
