That's fair and I agree with you that features need to be weighed against each other. But I really don't think a feature's presence or absence in another operating system should have much weight in a discussion about Linux. Nor would I assume that because another system made a feature tradeoff it's the right tradeoff, either in general or for Linux specifically.
