mhtml would somewhat fit part of the bill of what PDF offers: a single downloadable "file" you can archive or forward and you know: the recipient will see exactly what you saw.
however the mhtml doesn't look the same, depending on the device. and looking.exactly the same helps a great deal in convincing a judge that we all talk about the same.thing.
get me right.
I hate PDF with all passion of my heart. epub (similar to mhtml) imho is a much better format for many intents and purposes and it allows to reflow the contents depending on the device.
but the claim was "PDF is useless and.shall go" and that's cutting.it too short.
