True, but "fast" is a crowded concept in people's minds. If you look around the web you'll read that Firefox 4 is fast, Chrome is fast, Opera is fast. IE is "native" which is then connected with performance claims. It's a new name for an old feature that has a kernel of truth to back it up. I'm reminded of an early scene in Mad Men where a salesman convinces a cigarette company to advertise their tobacco as "toasted". Sure, so is everyone else's, but that doesn't mean that one company can't own that idea in the minds of the public.

A similar thing thing with the IE blog's new favorite phrase "same markup" which seems to be "standards compliant" in a new blue dress. Search the web for 'standards compliant browser' and you'll generally find folks heaping scorn on IE and praise on all the others. Search for 'same markup browser' and the opposite is true.
