What is the mass-market?

Just read a pretty interesting article: it starts from the recent MS Xbox 360 price drop and their statement that this brings it to the mass-market and discusses what the mass-market really means.

The mass-market isn’t "one thing for everybody", it’s "something for everybody". It’s not a Holy Grail, a monolithic audience just lying out there waiting for the Right Product – it’s a collection of niches, some larger than others, some very small indeed. Fill enough niches, and you can call your platform – and your medium – mass-market. Simply keep pumping your efforts into one or two niches, and you’ll always be on the sidelines.

I dissagree with the article in that I believe that price points are still a big deal in bringing everybody into games but the article does make some very interesting points. What do you think?
