A comment on CuMine supplies. After reading Sharky's

(If they're all out of stock, then it's likely there is indeed a tight supply of chips coming from Intel, which is surprising considering that they've dedicated four of their fabrication plants to the .18 micron process launch)

I may have an explanation for the low availability of CuMines. According to Aces Hardware, aceshardware.com, if a Coppermine CPU only has 128K of its 256K L2 cache functional, it is supposed to be sold as a low end Celeron chip, which would still be superior to the standard Celeron chip. (BTW, AMD will use the same strategy to salvage future Athlons with half-functional L2 caches.)

I suspect that on a lot of the CuMines being manufactured, the L2 cache is not fully functional or it is a speed limiting factor. The introduction of the 128K CuMine has not happened yet because OEM's probably didn't want to confuse the marketplace with new low-end chips. So Intel may be sitting on an inventory of 128K L2 Cache Coppermines.

It is also possible that the 128K CuMines don't work because of a design problem.

One of the two is true -- either Intel is building an inventory of 128K Coppermines, or something is wrong with the 128K Coppermines which will require (most likely) a mask revision.
