People who are actually working and not just drooling over hardware tend not to care as much about small fluctuations in performance (servers are of course a different matter; though even there things like reliability are much more important). When you're working at a workstation, people can hardly tell the difference until you *double* performance.
"Quantitative" data doesn't necessarily mean "better" data if its not measuring something terribly important.
In any case, whether you think its useful to have tons of benchmarks are not, there are a million sites already doing them. OSNews is doing something different.
