Again this is stupid...
Look, Apple is focused on having an Alti-Vec processor, everything has been written for that, now people say the new IBM Power PC based on Power4 might not be Alti-Vec so therefore Apple will not use them. If Apple is so worried about having Alti-Vec, then why in the hell would they be now going to an x86 from AMD. If Apple goes AMD or Intel it would have to be an x86 processor. That is what they build and they are not going to build a small number of some special high tech processor just for Apple, sorry IT IS NOT GOING TO HAPPEN.
Okay lets say you guys are right and Apple says...yep an AMD Athlon for our PowerMacs in Jan...then what do you do with the "i" and "e" series. Do you continue on with them as a PPC with Alti-Vec and make the PowerMacs with an x86 AMD? HOLY MOLY what a confusing thing. We then have Macs that are not even compatible with each other, you then have to make different software for different computers. What about all the PPC Macs that are out there right now. How long do companies have to make different software for all different types of machines? If Apple goes to AMD it would not be a PowerPC, and for now changing chip arc. would make for lots of confusion.
There is still something called AIM and PowerPC and this is where the future Apple processors will come from. Intel and AMD are not going to plug huge amounts of money into designing an all new chip that is completely compatible with PPC considering Apples market share. If Apple goes x86 then they might as well stick Windows XP on their machines and go head to head with the rest of the PC mess.
