I agree with this. Spending lots of time to change to a "real db" isn't 
likely to deserve being on the top of the priority list at present. Though 
I do think that keeping the thougth is a good idea, for example in trying 
to not needlessly further complicate a later switch.

This however, I disagree with.

A real db migth bring faster startup-times, which is important for people 
with humongous collections of pictures. I think this group of people is 
going to grow very quickly as the years with digital cameras pass. I know 
that my picture-collection grows by atleast a couple of thousand images a 
year, and I'm probably not the only one. 

Secondly, startup-time ain't the only reason a real database can be 
desireable. Another reason that in certain setting is atleast as important 
is multiuser-functionality. With a real database it should be possible for 
more than one person to work against a single image-archive. This is a 
showstopper for basically any professional or half-professional use where 
the users are more than a single person at a time. Similarily it should 
allow more fine-grained access-control since typical databases come with 
such built-in.
