It seems to be a common sentiment but I don't see much reason not to buy a PowerPC based Mac today if that's what you want. Let's say Apple was sticking with PowerPC. How would a machine bought today fare in 3 years? It would run all the software it runs today. It would probably run the software available in 3 years but be deficient in some aspects. Certainly, there would be vastly better machines available. How does the move to Intel change this scenerio?
