"I take it as meaning that MS is going to implement IE10 with as much low level integration to the OS as possible, i.e. it can make efficiencies by not having to support multiple platforms."
Then what they need to say, if they can prove it, is something more like "IE is faster than Chrome." If they're doing that at the expense of being single-platform, that's a tradeoff, not a feature to announce.
And if being single-platform doesn't make them faster than Chrome, what does this announcement mean? "Despite making this tradeoff, we are still bested."
Yup I actually agree with you. This whole native argument for me means speed when compared to multi-platform browsers, so if that doesn't turn out to be true, then there isn't much value in saying it (and a bit embarressing for MS).
My main point though was that all this talk has very nothing to MS introdcuing non-standard html5 in IE10, which loads of people seem to be implying.
