As I now have a chance for a response, I think it is warranted.

Intolerance?  No.  Suspicious of ulterior motives?  Hmmm.  Why would 
that be?

There are Microsoft tools you won't get from me without prying from my 
cold dead fingers.  There are Microsoft tools that are extraordinarily 
painful to use/deploy, that don't play well with the mainstream 
currently in use tools.  There are Microsoft tools with a, well, less 
than stellar security record or model.

Lets be clear about this.  The pricing (470, 100, ...) is *per node* 
correct?  If it is not *per node* and is *per cluster* this is an 
interesting scenario, and somewhat at odds with what people have been 
telling me over the last several months.

*per node* or *per cluster*

This is good.  I am glad to hear this.

As others have noted, the aggressive marketing campaign is a bit over 
the top.  Linux clusters have been "mainstream" and well integrated into 
corporate worlds for a while.  This could explain for example that the 
market has been experiencing explosive growth long before Microsoft ever 
entered it.

Be that as it may, I believe that there are specific areas where it 
would be quite valuable to have Microsoft work, and tap into the huge 
and rapidly growing market.  The replacement strategy represents a risk 
to users IMO if Microsoft tires of this (relatively small for them) 
market, and decides "no more".  There are other areas within HPC where a 
strong Microsoft presence would be good, in terms of interoperability, 
cross platform scripting/development, interface.  Not VBA everywhere. 
Mono with hooks to enable us to bind our languages in.

You might take pains to notice that some of us who are vocal critics of 
your companies actions and products, are also vocal critics of your 
competition.  I have been decrying the MPI binary interface issue on 
Linux for a long time.  This impedes progress IMO.  I have praised the 
DLL approach where one ABI for MPI would be supported (not one chip/os 
ABI, but application level ABI).  You might note that some of us heap 
appropriate scorn upon the poor choices of some Linux vendors (not 
necessarily the ones who sign deals with you).

As I said, there are Microsoft products that we will not stop using.

I personally would like to see some of them on Linux.  And I would pay 
for them on Linux.  As I am sure others would as well.  I pay for 
products that enable me to run them on Linux.  I pay for the additional 
license so that I legally can run them on Linux.

Now why would that be, if I were intolerant of Microsoft and their 
products?  Why would I be working hard to get the specific tools (Excel, 
Powerpoint, and to an extent, Word) available to me on this platform?

I wonder.
