I am simply commenting that IMO the people who hold the
strongest negative opinions about IPF in forums are often
the most ignorant about details of the architecture itself.
The previous poster's comments are an excellent example.

As it should be for the big picture view. I too am very
critical about some aspects of IA64 but only where it
is deserved - a few early design mistakes and repeated
instances of very poor product delivery execution that
have significantly hurt, to a large extent permanently,
the scope and extent of IPF's commercial success.

However in a technical discussion of the relative merits
of EPIC/IA64 vs traditional architectures one should at
least be generally informed of what IA64 is and isn't
all about. IMO most negative opinions about IPF at a
technical level is based on myths/misunderstandings
endlessly recycled, often by those with an ideological
predisposition to dislike Intel and its products.
