Given the amount of stick that Microsoft has received in the past about HTML standards compliance, well, I think these results really knock the soap box out from under some of the competition that like to trumpet their standards support.

yes, sure. yoo bad they do not list the acid test they fail miserably ever since the dawn of the metal age.
@Bob - The Acid tests are hardly about broad standards compliance (I won't rehash the whole debate that it is more about compensation failures) which is the point of the above testing so I don't see why anyone would expect an unrelated set of test results to be published side by side. But to your point, yes, IE has traditionally performed poorly in the Acid tests (11-12/100), however, I encourage you to review the current IE9 platform preview results where the results are already up around 55/100 and there is still a significant amount of work to go on IE9 before release!
...and the 3rd release of the IE9 platform preview scored 83/100 (up from 55 on the last preview release) so the IE team are making great improvements on this particular benchmark.
