By the end of 2005 about 270 legacy systems will be retired." The article also notes how the current ratio of packet traffic to voice is already 8:1.

    The problem with POTS systems is that you have to have the entire country wired with copper. A place that doesn't have the same huge investment in infrastructure that the US has is probably better off buying a used cell phone system and just running fiber between the towers. We may think of cell phones as being a luxury but that's only because we have 70 years of investment into copper to every home.
