I'm really late on this subject (been out of town) but I have some thoughts. I think a lot of us are speculating too much (I know it's a rumor site). What I think it comes down to is business and Steve Jobs. Motorola increases speed too slow to compete - IBM steps in and says 970 and 3 GHz in a year - IBM fails to meet that mark. All the while OS X is ready for X86 or PPC. Steve (a bit angry at IBM and the repeated Moto pattern) looks at all the options. It appears that Intel has the brightest future 2 years down the road. (Maybe IBM didn't sell their future as well or based on past/current experience Steve doesn't believe them). Intel seems more secure, more reliable, faster moving, more options, cheaper computers as a whole, etc. Apple switches. I don't think IBM is trying to save face or Steve was just putting pressure on them to get them to come out with better products. This is too much soap opera ish.
What I would like to see...IBM, Motorola, Intel, AMD and anyone else who would like to really innovate and fight against each other in terms of product performance, power consumption, price etc. Apple sets themselves up to implement PPC or what X86 turns into through this universal binaries thing (and that it is universal in terms of PPC, X86, 32-bit, 64-bit, Altivec - whatever). Then at any given time Apple releases updates with the best hardware for the computer.
We the mac users get the best hardware at that moment with of course the best operating system from Apple and hopefully none of the problems that plague the windows world.
Back to more on subject - IBM announced these because they have developed them and the want to sell them now. I think that's about all there is to it.
