Individuals interpret value v. price very differently. These are not
the same, nor are they reasoned by individuals in similar ways at all.
One approach in examining what value, if any, exists along with the
price (whether it be the PS3 or other computer) is to compare computer
processing performance of Cell v Intel, in this case a Mac mini - since
they are offered at about the same price. One could also take the time
to compare other Intel computers selling for the same price. A quick
view of just what is available within the same price range may be
revealing, here are some links:

The specs for the Mac mini, as mentioned elsewhere, are here:
http://www.apple.com/macmini/
One of the most infuriating aspects of interpreting the technical
information Apple provides has been comparing what they present against
standard fundamental comparisons which other vendors use. However, many
companies don't present that kind of information in a format which is
plainly or easily discoverable.
So let's use what can be found quickly.
In considering this particular problem I found 2 meaningful sources,
from amongst a flood of others, referring to the Cell:
1. 2 straightforward meaningful numbers from here:
http://www.ps3.net/ps3-specs.php
2 numbers which caught my eye are:
1.8 Tera-flops floating point performance for the GPU
2 Tera-flops System Floating Point Performance
2. A different report from the ISSCC:
http://www.realworldtech.com/page.cfm?ArticleID=RWT022805234129
This report is perhaps more interesting than others which have been
referred to because it's purpose is to clarify and analyze, as opposed
to present something impressive. They mention what is often overlooked,
1Tera-flop is equivalent to 1 Billion instructions per second.
Let's return to Apple's Mac Mini whose floating point numbers are on
that same page. What is that value? 26.3
Now let's be fair, Apple is comparing it's current model against it's
older one -- and there is a significant improvement.
That is not what interests me here. I am interested in extracting
information which will help me ascribe a value which can help inform my
personal view in comparing against another similarly priced computer.
We have 26.3 floating point compared against 1.8 Teraflops floating
point. That's 1.8 Billion instructions per second for processing
floating point based calculations. In the fields such as advanced
financing (Stock Market institutions), and sciences (dna processing,
muscle and nerve innervation analysis, biochemical analyses of all
sorts, astronomy, weather analyses, earth sciences, etc.) where tiny and
unimaginably huge values are are needed to analyze interactions and
events accurately the access to such technology is of huge importance.
These people have homes and families (who themselves may appreciate an
inexpensive computer they can reliably work with utilizing advanced
precision) , and other persons not as well established in their careers
or life who have the knowledge can certainly utilize this kind of power
and make their own contributions in these same fields as well in various
ways because of the open source concept and a free web, via this same
inexpensive system.
Although I did not discover the system wide performance numbers for
current Intel based machines I frankly don't have that much time to
pursue this question further. However, I have not heard of any other
computer system being at anywhere near 2 Teraflops for system wide
floating point performance, except the Cell (a joint venture of Sony,
IBM and Toshiba).
There are other computers performing at the level of the Cell or
better. However IBM according to the NY Times, Feb. 9, 2006, "IBM
Unveils Server Line That Uses Game Chips" by Steve Lohr, sells those
computers starting from 20-30K ($20,000 - $30,000). Given this added
published fact, the value in my view is with the Cell. For $600 there
is the opportunity and chance to learn and acquire skills approaching
that used in very high end systems. In my view, that is value indeed.
I personally comprehend what that value is because I have accumulated
over 15+ years of technically advanced work experience with high end
computer systems from IBM, Stratus and others. I have a profound
respect and great enjoyment in having worked with these advanced systems
and look forward to the continued availability of such powerful systems
returned to the public and commercial market at such an amazing price.
