That doesn't mean anything ! Any scanner can do 72dpi.
If you want to speak of quality concerning resolution,
you have to check the maximal resolution. But anyway,
nearly all scanners can make resolution high enough for
most purpose.

What count is how acurate the colors are rendered
(like Spoon explained) and the usablity of software
that comes with it especialy if you are doing a lot
of scans.

Seening you speaking about dpi for pictures displayed
on a screen seems to indicate to me that the program
you are using isn't very good. (no offense mean) :
dpi is __totaly__ __utterly__ meaning less for computer
screen : there is no "dot per inch" but resolution. Which
is a number of pixel in width and high. If you are
using a 800x600 resolution on a 15inch screen, the
pixel will be smaller than if you are using the same
resolution on a 19inch screen. But the number of pixel
stay the same : 600x800 !

So you can scan your picture in 10dpi, 72dpi, 300dpi,
1200dpi or whatever else you fancy, it won't change
a damn thing as your software/scanner will reduce/enlarge
the picutre to get the number of pixel you want.

Ie: the scalling factor and the dpi are linked together.
When increasing the dpi, you have to reduce the scalling
factor to get the same number of pixel. When lowering
the dpi, you have to increase the scalling factor to
get he same number of pixel.

What count is the number of pixels for displaying on
a screen. Not the dpi/scalling factor.

dpi is a unit for _printing_ when the number of dots
you can put in a fixed size area change. (Ie: you
can put more or less dots in the width of a page
depending of the resolution(dpi) of your printer.
While on a screen at a 800x600 pixel resolution, you
can always put only 800 pixels in width).
