I learned from a book on small business that demographics is useful in in showing who buys while psychographics is useful in showing why they buy. Without demographics you are constantly chasing after new customers and without psychographics you are just guessing what they want.
It sounds like in your articles when you are talking about what job the customer wants to get done you are talking about psychographics. But how can we know that without knowing who the customers is?
I agree terms like casual and hardcore are ineffective ways to segment the market because they are just labels with no specific target at all. Anyone can easily fit into either category. And the reasons for people belonging in the these category’s changes depending on who you talk to. What’s even worse is this typically means decade old stereotypes are used like actual demographics.
But a real understanding of who your customer is, is still needed before we figure out why they buy your products.

If you meant demographics as in population numbers, of population growth and decline, you would be zeroing in on a cornerstone of the DS and Wii strategy. Both the DS and Wii were designed for gaming to survive in the midst of population decline. But I don’t think you meant it that way.
