This is an interesting point, and one that is rarely addressed.
On a film SLR, if motes of dust enter the camera while you're changing 
lenses they will likely land on the negatives/slides of at most three 
photos--and the area they have to land on is  35x25mm. But if the same 
dust enters a digital SLR and lands on the (roughly) 15mm square CCD 
chip that captures the photo (with its 3 or 4 or 5 *million* pixels), 
that speck of dust is there for the duration and will affect every shot 
thereafter. Simply having a digital SLR cleaned professionally will hit 
your wallet to the tune of $200 or more. This was one of the strongest 
selling points for me when I was considering which camera to buy. For 
the non-professional user, I truly think a fixed lens digital is the 
only way to go.

Good advice, Knut Erik
