Arpad, when Intel does start releasing AMS models, won't that make them one 
of the first IC vendors in the world to do so?  If we were to count out the 
list of IC vendors and models available in AMS:

a) Today
b) Planned for the next six months
c) Planned for the next twelve months
d) Planned for the next twenty-four months

How extensive would that list be in each category?

Regards,


Steve.
