The DECT phone standard had to be marketed as "6.0" for the US market because non-technical people were trained to believe that 5.8GHz was better than 2.4GHz and a phone that ran at 1.9GHz would never sell in the US. This is the same thought process driving the audiophools' desire for bigger numbers regardless of reason. It doesn't help that the fundamentals of sampling theory aren't particularly intuitive.
