On the Antique Road show(PBS) one Queen Anne sideboard was appraised at several thousand dollars. The appraiser went on to say "if it hadn't been refinished it would be worth over a hundred thousand". The hardware advances coupled with the hundreds of new instructions allow z/OS to progress and evolve. In Dr Webb's rollout paper for the G6/Z6 he points to the use of 62% commonality and addition of cache strategies to accomplish thruput improvements mated with z/OS instruction set on a base processor with 176,000,000 transistors. These are not trivial pursuits. The Global Foundries fabrication center is a multi-billion facility with continual updates and modifications. _www.globalfoundries.com_ (http://www.globalfoundries.com) Guess my point is for all it's warts and wrinkles z/OS is here and evolving as it carries a large workload for Fortune 500 companies.
