Well said! And, I might add, it shouldn't be necessary for us POV users to
have to become computer scientists or programming/architecture experts just
in order to understand why 64-bit POV on a 64-bit machine is faster (or
slower) than the 32-bit one. Simple, real-world benchmarks would
suffice...not a lot of holier-than-though technical browbeating.
