M9 most certainly does have a mirror. How do you think you see the focusing patch in the viewfinder? It's not a
reflex mirror (which I think just means "leaning backwards" not "moving out of the way" as in "twin lens reflex" where the mirror is fixed) but the Leica M is still a very different beast from what the rest of the world thinks of as "mirrorless".
SLTs use a reflex mirror as well. I wish Sony would use the term
pellicle rather than "SLT". "Single lens translucent". What? The lens is translucent? Lets light through? Unlike any other lens? You may compose your shot using data read from the sensor with the A99, but it's not only inaccurate to call the A99 mirrorless, it also goes against the common understanding of the term when applied to digital cameras.
