Well. I plowed through it best I could. Apart from two learned men arguing like a couple of kids, I could not see anything in it where Howerda postively disputed Kennedy's findings about 7.
There have been several more benchmarks since then, all confirming that this release does not outshine Vista or XP in any particular fashion. The point which was not emphasised enough, is that it is ludicrous to benchmark a two year mature OS with a release which has not yet even reached Beta stage.
My own immature and inexperienced comparisons, in an earlier post on this site, concluded the same thing. In fact, with my customised and well tuned Vista, I was able to produce, in several instances, better performance.
But I would not be so bold as to slam Windows 7, at least one year before it's final, and , hopefully, mature release.
