Bash where it hurts...
When coppermine was introduced, Intel wouldn't ship it at 550MHz .25u speed grade but rather 667, 733MHz. And, guess what, the pipeline wasn't stretched 50%.
First Northwoods would follow Presscott pattern but was never advertised at a frequency over Williamette's 2GHz. Right after the secod stepping was ready Intel announced and delivered 2.4GHz immediately, not the case with presscott.
While there may be some bashing, you're clearly on denial.
