Traditionally, hardware and touting your system's "specs" has been bragged about from playgrounds to workplace lunchrooms. This "system" can put out better graphics, this system can do "this" and "that," and on. I get extremely annoyed with people who engage in this type of salvo because it is eerily similar to gym room banter about the size of "my" cock versus "yours."
Currently, each console has an interface. Microsoft has Xbox Live, Sony has the Playstation Network, and Nintendo has the Wii Menu. Each is different with some being more fully integrated and easy to use than others. This leads to the question,
When will interface supercede hardware in consoles? At what point, will buyers decide x console has a superior interface to y console, thus forth I will purchase this console regardless of the hardware specs.
So what will it take? Equality in hardware between the consoles, which we have never seen? Digital distribution only as the mainstream way to purchase games? Or is such a question implying that consoles are on an evolutionary trend to become PCs with a television as the monitor?
