Thanks for reminding us about that 2008 article:
As Peter Oppenheimer said at the recent earnings call, this innovation is something "Apple's competitors won't be able to match for some time to come. We expect the process to drive down the prices of MacBooks over the next few years and at the same time allow Apple to continue to lead in the innovation department. Design changes should come much more rapidly with rapid prototyping."
That's why we do see much more frequent updates, always showing the latest state of the art intel cpus. And body modifications which would reflect latest insights of ergonomy, instead of wrist cutting corners which were a design flaw of the first unibody MBP - not to speak of the great improvements in screen variations, offering matte options for the 13"ers again. Oh, and I forgot to mention the most significant price drop which was obvious to everyone...
Yes, I really do see how this once new process significantly changed how Apple now does offer new and improved models.
Hm, how exactly is this new MB better than the former ones?
BTW: AFAI read no one mentionned scratches on these soft plastics unibody MBs - they do look ugly after just a few weeks.
