Not sure if this should be in hardware or this so move it if it's in the wrong place but isn't there a lot of rumours that the new ibook and mac mini is going to be single core. Wouldn't this make no sense since as far as I know they've programed mac os x for duel cores. Plus wouldn't this make it harder for developers since they wouldn't know if the user was using single or duel core.

It was programmed for both as far as i know, but they are also using not the traditional OSx but the x86 version as i think the new mac mini and ibook will be some of the first of apples intel machines.

currently:
macbookpro - intel (the only one)
ibook - g4
powerbook - g4
mac mini - idk, either g3 or g4
imac - g4
powermac - single or dual g5

i'm sure they may switch the others to intel in the future, but i'm not in favor of it. i dont like intel, but liked the ppc series.

Actually the macbook pro has replaced the powerbook and the imac is intel as well. Steve Jobs has said that all their products will be intel by the end of the year.

They are using the new duo cpus from intel in them, mind you they are still macs and they still cost far to much.

everything meaning everything will be dual core by the end of this year

apple says its the best way to go for the future

who knows?

powerpc's are going to be gone! noooooooooooooooooooooooo

Well quad and 8 core are coming out this year as well so well be beond dual core in some cases.

Its not the end of power pc, Power pc chips power the Xbox 360 and the PS3 has a cell processor which actually falls under the PowerPC chip brand name(and interesting factoid but thats what IBM are calling it)
