I shouldn't be bitchy about competition, but this does include some 
amazing revelations:

"The LS-4000 ED is a FireWire/IEEE 1394 device, a virtual necessity (at a 
400-Mbps transfer rate) due to the enormous amounts of data it can 
generate."

and

"Preview scans took 20-40 seconds, full-resolution scans required about 
100 seconds to create a 67-MB (!) file."

= a data transfer rate average of 670k/sec. OK, the scanner is probably 
doing carrier-positioning and AF and other stuff for a good proportion of 
that time, so the data rate is probably somewhere between 1.5Mb/s and 
2.5Mb/s = exactly the same as most other scanners working over SCSI or (at 
the lower rate) USB. So the first sentence is complete b*ll*cks then.

"And the LED light source is also somewhat collimated, meaning its light 
waves travel in relatively straight lines." 

Gosh. Presumably Nikon have developed LED's which avoid generating the 
extreme gravitational fields found in other scanners, that also causes 
Saturn rings of debris orbiting round your house and sticking to the film.

"Overall, there's no question that the LS-4000 ED sets a new standard for 
desktop scanners in the sub-$2,000 category.
...
In all our prior film scanner reviews, the highest resolution we'd 
encountered was about 2800 dpi." 

Oh dear. Now I remember why I started reviewing FS...
