High cost, no good compilers, and poor availability of documentation so
people could actually take advantage of a very cool processor design...
Oh, and relatively low clock speeds.

Which, when one's shopping, means to look for em64t instructions on the
Intel chips in consideration if one wants the backwards-compatible Intel
64-bit implementation.
