Totally underwhelmed from a photographers point of view. Same head technology and factory tech only mount, basically the same inks, it seems the only difference is the roll paper cover gets a black finish on the 7000/9000 compared to the regular silver on the 6000/8000.
My 7900 died after 264 prints, my 4900 I had to take the head off and clean it myself (but it works again) with 1294 prints, I'll see what Canon bring to the table with the iPF6400 replacement, but that is most likely where I am headed.
