I'm not sure what your asking here, but this is my take upon what i think you mean. Heck i could be 300 miles off/ Note, i'm getting this frrm assumptions that i'm making about a few roadmaps i've seen.
The celly is here to stay, getting the .13 micron treatment sometime in the future. The p3 .13 is mainly designed around use in laptops until intel can make a "low power" version of the p4. These desktop .13 p3 are, well not really high end nor low end, they are kinda in a Hazy middle ground. The 256k cache ones, look to be built for everyday consumer use, and the 512k ones looked like to me, by viewing Digit-life's intel roadmap, ment for highend laptops, Duel processor machines and high end workstations. Either way, this is the end of the line for the p3, these chips are just to fill in till the .13 p4 starts to shine..
EDIT: I don't think the cellys dead for the budget chip, LWD's roadmap shows this...815G/EG and 810E/E2 chipsets will support 0.13 micron Celeron CPUs in Q1'02 processors..l. So there not dead yet..🙂
