Well, and the other part of this (which we've discussed a number of times on this list) is the notion of price discrimination. It's no different from airlines selling identical seats at very different prices to adjacent passengers. It depends on when you book, when you are flying out and returning, and all sorts of similar things, but essentially it boils down to your willingness to pay, and the ability of the airline to evaluate this. If you want to fly tomorrow and return the day after you will pay much more than someone who wants to fly next month and stay over a weekend.. If you want to run a COBOL workload and have no other place to run it, you will pay much more than someone who wants to run a Java workload that could just as well run on a commodity Intel box costing a tenth the price. Customers continue to find flaws in the enforcement of these schemes, and airlines/IBM fix them as necessary to keep the bottom line in line. Whether Scala or COBOL on zIIP is enough of a flaw to provoke corrective action, I don't know. Right now probably neither is, but that could change.
