I find the economics of this new printhead quite interesting. With the old one, when you had to replace it, you were only wasting half the ink. Of course, if both had to be replaced within weeks of eachother, which was usually the case, then this point was moot. If anything, having to then buy 2 new heads was likely more than twice as expensive as if it was only one.
So going forward, how much more expensive will this new head be seeing as its essentially doing the work of what you needed two heads for with the previous printers? Canon should be selling half the number of heads now, so will they really want to pass this cost savings to consumers? Or will this actually lead to a cost savings for the consumer with this new head design now being twice the price of the previous head since we needed two of them.
Also, given the configuration of the colors, its not like you had one head which had the top six used colors, while the other had the 6 least used ones, which could theoretically mean that you were replacing the lesser used one much less frequently. Unless there was physical damage to only one head, most issues ranging from regular use to electrical issues usually meant that both were replaced.
There are simply too many factors to consider, but I do find this quite interesting.
