The odd thing is that HP, being the only manufacturer of the three with a build-in spectro, has more clients for whom the HP papers are enough, and thus with less need for profiling (HP includes the canned profiles at the website) then the others.

The spectro is the difference between "sorta kinda close" and "spot on." And the spectro gives you the ability to recreate profiles to adjust to subtle changes to the printheads, inks, media, etc. over time if those things occur.
