I just saw the information on new 12 inch PowerBook. Awesome machine, I have to say. It is the answer to people (me included) who's been saying "I want an iBook with G4". But, this 12 inch PowerBook looks so much like iBook that I can't help but wonder if they share number of components. For one, I wonder if the 12 inch screen is identical to the one in iBook, which is not as good as the ones in latest 15 inch PowerBooks. And I wonder why they limited the RAM to only 640mb, just like iBook? Even the optical drive, even though it is slot loading, is exactly in the same position as the iBook. But some of these similarities could be simply due to form factor. One obvious difference I noticed is that 12 inch PowerBook doesn't seem to have visible speakers unlike the iBook. I wonder where they moved those to. The specs also mention that it has THIRD speaker, designed to enhance midrange sound. I wonder what this might be? If you have any other observations, thoughts, or ideas, please comment.
