Ask HN: What are the implications of Apple moving to 64-bit architecture?
It's very difficult to find anything related to this subject that hasn't been overshadowed by either "4GB RAM" or NSA discussions.
Is there anyone out there that can give an overview of what this move to 64-bit really means?
Does it signal Apple hoping to develop the A7 into the notebook/desktop lines of computers?
