Thank you for the flowers, Nick.

You make it look a bit like I knew my stuff better than others and I 
would like to discount that and rephrase this into "I know well what I 
don't know and I stay away from that". I would feel rather uncomfortable 
if I had to resort to making assumptions. This is why my choice of 
subject matter may at times seem out of balance as in "Oh, no, not 
'roaming' again ..." ;-) Other than that, I am pretty confident that you 
know your stuff just as well as I do mine.

I am sorry to learn that the points I put forward seem to lack 
structured argumentation. I promise I will try to work on it but I have 
to digest this first ;-)

Taking on your comments above, I think that in the interest of a 
structured argument it is wise not to pick quotations and explain why I 
think they match the formula I presented as it may turn out to end up as 
rhetoric. Instead, I would like to provide a logical examination.

I may have a misunderstanding, but my reading of the various responses 
received yields a number of statements that in my understanding appear 
to be saying the following ...

- Japanese phones are cute and therefore PDC is good

where PDC may also stand for the domination of PDC

- Without PDC there would be no cute phones

where PDC may also stand for any proprietary domestic cellular system


Let's now examine this on a logical basis ...

We have a claim that goes like this:
    (1) Japanese phones are cute therefore domination of PDC is good.

And we have also got a claim that goes like this:
    (2) If there was no domination of PDC then there would be no cute 
phones.

Or in a different notation:
    (C1) Cute phones exist => Domination of PDC is good
    (C2) Domination of PDC exists => Cute phones exist
    (C3) No Domination of PDC => No cute phones

C1 and C2 are due to (1) and C3 is due to (2)

I will now show that C1 - C3 together will lead to the logical 
equivalent of the formula I presented, which should serve as an answer 
to your inquiry

By substitution of "cute phones" with "shiny piece of metal" and "PDC 
domination is good" with "all is gold", C1 can be directly translated 
into:

	(A) If there is a shiny piece of metal then all is gold.

 From C2 and C3 we derive that the existence of cute phones is a result 
of domination of PDC and the absence of cute phones is a result of an 
absence of such domination of PDC. Thus, if there is an absence of cute 
phones then there must be an absence of domination of PDC.

Because of C1, the existence of cute phones also leads to domination of 
PDC is good and hence the removal of cute phones removes the indicator 
to render PDC dominance good.

Therefore, by substituting as above we will arrive at:

	(B) if there is no shiny piece of metal left then all is not gold.

Combining A and B, we get:

	If there is a shiny piece of metal then all is gold,
	until there is no shiny piece of metal left.


What I was trying to say by this is that you cannot judge an entire 
complex by cherry picking one particular piece of it that may be 
favourable. That one piece may not be representative.

Apart from that, there would also appear to be some confusion about the 
fact that the discussion got frequently side tracked resulting in two 
different discussions going on in parallel, one of which in my opinion 
had nothing to do with the other.

My argument is based on the overall macro-economic complex of a wireless 
infrastructure. That includes consumers, operators and manufacturers; 
shareholders and employees; and the impact on the economy which they 
rely on to act and function.

I don't want to go into details again, because I think we have gone 
through this often enough by now. Therefore I am trying to summarise my 
argument on a very general level

I am saying that the Japanese economy (including all entities which are 
active in it) would have done far better if decision makers had bothered 
to take into account that Japan is an export nation relying on exporting 
value added products (as opposed to commodities).

The Japanese government has realised this some time ago and they have 
acknowledged that it would be beneficial if Japan had adopted GSM (their 
first choice) or CDMA (their second choice). They intended to change in 
1996/97 but found they had locked themselves pretty well out. So I am 
not preaching any new gospel. Fact is there is no dispute over this 
(other than some readers on this list perhaps).

Countering my argument, I keep reading things like "not true - Japanese 
mobile phones are cute - therefore you are wrong".

This has led us to get somewhat distracted from the main argument, 
because a side issue of "these phones are better than those ones" popped 
up as a result.

Independently of the main argument, I happen to disagree with what would 
seem to be the consensus on the *side issue* on this list, that Japanese 
phones are superior. But whatever my opinion on this side issue is does 
not matter, for it is a side issue. Even if we were to agree on the side 
issue, that Japanese phones are superior, even then, the main argument 
stands as it is. In fact no matter what we were to agree on the side 
issue, the main argument still remains unaffected.

I am saying, whether Japanese phones are superior or not does not matter 
for the main argument. However, I keep reading responses along the lines 
"not so - if Japanese phones are better then so must be the Japanese 
phone system" or "Japanese phones are better therefore you are wrong".

That is why I am saying, you cannot cherry pick one particular piece 
(the judgement of which is arguable anyway) and judge the entire system 
based on that one single piece.

It doesn't work that way.
