The Microdrives that most folk use in pro digicams (such as the Nikon D1)
are tiny hard disks.

The pro digital SLRs I've used are *very* sensitive to dust. You change the
lens (not something that's easily avoided), dust gets into the body, finds
its way onto the sensor surface and hence onto your images.

The sensor is *very* difficult to clean in the field, you can try putting
the shutter on B and spraying the sensor with air, but IME it doesn't work
very well. Usually it's a tech job.

At the same levels of dust and dirt a conventional camera just keeps going.

In practical use, dust on the sensor is a *serious* problem.
