What people are failing to realize is that the DMR is a compromise to 
carry Leica through until they have a dedicated Digital SLR.  As part 
of the compromise, the battery had to be small, so the whole package 
fit into the design parameters, which was meeting the size of the R9 
with a Motor Drive.

The images though out of the DMR seem to be first rate and not 
consumer digital quality.  On person on another forum reasured a 12 
stop dynamic range with his DMR.    I don't think any other digital 
SLR can match this.  The color is also 16bit compared to 12bit for 
the rest.  Between the dynamic range and the color, DMR images have a 
look of no other Digital SLR.
