conditional comments are not features detection. I would rather do something
like:

xhr: window.ActiveXObject ? function(){return new ActiveXObject
("Microsoft.XMLHTTP")} : function(){return new XMLHttpRequest}

but I guess it does not make sense since xhr performances will never be a
problem (we do not create ajax call in loops, for example, do we?)
