Every thread I read so far said, that you can still buy a PPC based Mac because each app will run on both platforms from now on, because of the "universal binaries". Now, where do you get this knowledge? Is it because Steve Jobs said so? I'm sure Apple's apps will run on both systems. I don't doubt that apps like MS Office or Photoshop will run on both systems. But I somehow doubt that every single developer will make their apps processor independent, as soon as the switch began or ended, just because Steve Jobs said so. It would mean extra effort after all. So what makes everyone so sure, that the PowerPC will be supported not only by Apple in the next years?
