Thank you for your responses. They helped me clarify waht was being said
and understand the two positions better. Technically, it is beyond my
understanding and ability to deal with the engineering and physics specifics
of the arguments; but theoretically, I get the gist of the arguments being
made by both you and Anthony, which is helping me develop my position on the
subject.

Here I do agree with Anthony. CYMK is a fundamental element in almost the
entire printing process - even if in some areas it goes seen but unnoticed.
You do not directly deal with CYMK when outputing to inkjet; but the printer
converts to it and prints in that space as limited by the media and the
inks. It is the CYMK output that one is trying to match in WYSIWYG.
Monitor displays are RGB but they make up only a small portion of the final
finished outputs both in terms of images and in terms of textual materials.
The Web may rely in RBG displays but most materials found on the web at some
point is downloaded and printed to hardcover by a goodly number of people.
Most bureaucrates and business people demand hardcopies of everything for
safety reasons and as backup which is why the "paperless society never
happened.

I fully agree. It wouldn't be the first time they tried to cripple
their lower-priced products so as to force many desktop users to
upgrade to a more expensive alternative.

Absolutely. The limit there is 2^64 bytes, which, however, is so large
that I don't believe we will ever have to worry about getting close to
it. My argument for this is that 2^64 is a 20-digit number and thus
comparable to the number of silicon atoms in a complex electronic
device like a CPU or a memory chip. Unless something about electronics
changes drastically at some stage, we are never going to reach that
limit. By the time we reach only just 40 bits of actually used address
space in a desktop computer, all modern computers including PowerMac
and new architectures like IA64 will be in a museum anyway.

A fully agree. The inefficiency of using >4GB on x86 is not
significant, however, because most of the workaround is done by the
memory management unit, which doesn't introduce any delays at all. It
does, however, limit the memory space allocated to any one process to
4GB, that is a real limit of the x86 platform that is very hard or
impossible to get around without radically changing the concept of
linear address space inherent in all modern desktop operating systems.

That's right, sRGB was made as a universal compromise, not a panacea
for all colour problems. For critical work, a properly calibrated CMS
is still necessary, but in this respect LCDs and CRTs are no
different.

That reminds me of a question I sometimes ask myself -- how many
people still use CMYK? I can't see the point of using a colourspace
like that that has nothing in common with either input or output
devices.
