I used to own a 12" PB 1.5 Ghz with maxed out RAM and I loved it. I have since handed it down to my mom, who adores it because of it's portability, especially compared to my sister's G4 iBook. I have moved on to Apple desktops now, and though I do not crave for another portable, I am wishing for Apple to come up with a replacement for the 12" so as to satisfy the need of those who are looking for a Mac with even more ultra portability.
In my wishful thinking, this is how I see it: knowing how Apple always comes up with something that is revolutionary (e.g., iPhone), something really might come out and be a successor to the old 12". Something that uses Flash Drive for memory instead of HDs perhaps, to make it even more thinner? (Because what is the point of coming up with something that is similar with the old one if it still weighs in as hefty?) I have read about these flash drives; if they do come out with something over 60-80 gigs, then that would be something! It would make the new version thinner, and the battery life will probably last longer!
Oh, well, wishful thinking.
