But you also only see your little part of the world.

It is, but you've got a problem, when you have
one or more companies who's applications you depend upon.

One application that I currently have to support, is pretty much THE
central application for the company I'm currently working for.
For example it needs Java in a specific version, which for one  
I doubt I can get for AMD64 (it is too old 1.2.05b2). The vendor 
ported the application to Linux and I know they have it running 
at some Asian client site. It will probably take ages to get the 
application ported to AMD64 and then they will certainly not use 
something that will cut them off from all the legacy/commercial 
stuff they depend upon (Sybase/Oracle libraries, numerical libs etc.)

So from my perspective pure AMD64 is but a toy (a nice one I admit), 
whereas a biarch is something I could actually use at work to build
up compute nodes in addition to our Sun E6800 cluster.

That depends on what you define as long-term ?
 3-5-10 years ?

If you say 5-10 years, then I certainly agree, but but in any 
timeframe less then that it definitely matters a lot.
