The PowerBook G5 could have existed

Now that Apple officially unveiled their 970MP, IBM began to communicate freely about this CPU.
That's why we learn in a communiqué (HERE) there now are low consumption PPC 970FX. Two models exist, a 1.4 GHz G5 consuming 13W and another 1.6 GHz consuming 16W. Those are typical, but not maximal consumptions.
Those who feel that Apple was too quick to abandon PowerPC will find there some argument to feed their resentment. Yet one will have to follow what IBM will offer in the next years (though their partnership with Apple being down, R&D might slow down), to know if this difficult choice was a good one.
