The big problem I have with the TFA is that it states that the purpose of niche products is to drive innovation among the market leaders. From a whole-market perspective, that may be the role they end up fulfilling, but that is not their purpose at all... their purpose is to make money for their producers. Failure to enter the market strongly is still failure.
There are many different ways to look at the purpose of a thing. You seem to be identifying the intention of the company which owns the console. Another definition of purpose (more in line with telos) would be the actual effect it is destined to produce. That seems to be how this usage is to be understood.
