announced the new CPU model so fast, it doesn't like a desktop computer ..I

market needs??? ..just curious...if you upgrade the mianframe currently I
think you also have a question...
I think it is matter of development. Sometimes changes are minor - like
new cards, even new features (STP) or "turbo" sub-generation (z/900
2xx). Sometimes is is new model, because the changes cannot be
implemented in existing one.
Is it too frequent for you ? Then stay with old machine.
Why status of competition should influence frequency of changes ?
