Turning inkjet printing on its ear

yndy pointed out this announcement about Australian company Silverbrook Research's new high-speed pagewidth inkjet printing technology.  Some technical questions exist, but it looks as though this could revolutionize inkjet printing.  How would you like a $200 A4/letter size printer that prints one full-color page per second?  Maybe a photo printer that spits out a 4"x6" full-bleed print every two seconds?  How about a 51" wide-format printer that prints photographic images that can print a four-FOOT by six-FOOT full-color photo poster in six to twelve seconds?
