You don't put an experimental design into production on day 1. This is similar to the classic "let's rewrite the whole thing" problem. Maturity of a platform is an important factor, and it's often difficult to pinpoint all of the particular aspects behind the maturity of a given platform.

Intel made the same mistake with the IA64/Epic/Itanium architecture. They were banking on that to be the future of high performance computing and then AMD kicked their ass by using an iterative approach with x86-64. The irony is that today the Itanium architecture is actually pretty good, finally, but it's been relegated to a tiny market niche.
