Part of the answer is in expressivity -- in breaking down problems into simpler, combinable parts. Like Unix pipes or lego But as expressivity increases, the number of combinations increases and hence complexity itself increases. This is first hard lesson learned for those that approach the challenge of achieving simplicity. The first idea one has is ‘I’ll break everything into the smallest little parts’, and suddenly you have a thousand little parts. Sony products were considered extremely fragile because they were constructed out of tons of small parts. If you dropped it once, every little piece would fall off. Compare that to the Mac unibody.
