So far I found this about the ColorQube at Greg Walter's Death of the Copier posted in May 2009.
Advertised as offering full color pages at 85ppm for $23,500Then I found Andy Tribute's column at WhatTheyThink posted in June 2009.
This product line has five models ranging from a low end 90 pages/minute ComColor 3010 at a price of $25,194 to the top of the line ComColor 9050 running at 150 pages/minute with a price of $46,194.But there are so many more issues to consider.
It would be helpful if someone could do a side by side comparison on a printable A4. It would be much easier to compare and contrast. If they added CodeZ QR + a human readable pURL, a dealer would know who was looking at what, when. They the dealer could make the phone call or send the email, start the real conversation, and maybe close a deal.
