If your point is that there is a trade-off to modularity, I'm not sure who it is in response to. It's obvious that modularity has a tradeoff. And I don't see any significant group in this conversation contending that. Nobody is asking for a user-replaceable RAM on an iPhone.
My own point (and R2R's I think) is that Apple, in most cases makes hard to repair products not as a tradeoff in favor of simplicity/compactness/robustness, but to increase profit.
