Fine tuning product needs

I am constantly fascinated by the kind of technological products that are available in the market. Well, not just by the products but by the amount of specialization that we are going into these days to arrive at extremely specific products such as these EMI Shielding products by New England Die Cutting (NEDC). Earlier it was quite acceptable to produce something that was alright for several purposes, but now each product must have something specific in mind or fix a specific problem.
