I can't give you a consensus, but I can give you an informed opinion
having had the opportunity to tour the HP R&D facility in Barcelona,
Spain and partake briefly in a feedback group prior to the Z series
release.

I saw a multimillion dollar facility with tools more reminiscent of a
NASA research lab than what I had expected for ink jet print design.
There were separate labs dedicated to features like ensuring the print
head track is true to an incredible tolerance, so that exacting
precision is maintained throughout the head travel. There was a series
of temperature controlled rooms where printer mechanical function and
print output quality were studied under conditions ranging from near
desert heat to refrigerator cold. One lab ran a high power industrial
microscope attached to a high speed stroboscopic camera to actually
film the droplet size and shape characteristics of the ink as it was
released from the print head in real time. And repetitive failure
testing put critical parts through simulated life spans far in excess
of what even a busy studio or lab might consistently perform. And this
doesn't even begin to consider the thought put into co-development
features such as teaming with Gretag-Macbeth (now X-rite) to
incorporate a real full color spectrophotomer for on the fly
simplified color calibration, or working with respected paper
manufacturers and chemists to craft ink and receiving media which
compliment each other for both quality of output and archival stability.


Needless to say I was very impressed. I'm not naive enough to think
that other manufacturers don't have similar facilities, but the effort
expended in seeking and then implementing the feedback from real world
professional users set HP apart from what I have seen and heard about
Epson. While HP was late in seriously committing to the high end
digital photography market, I'm convinced that they produce a quality
product. I know that there will be unfavorable experiences for some
with any manufacturer's design, but my first hand experience with the
130 and now Z3100 have done nothing but reinforce my positive feelings
about HP products.
