I very much doubt that. In fact, I think people are just not writing the
apps because the DB layer is hard to find/use/whatever.

Examples of applications where a DB makes sense:

Recipe app (KRecipes)
Mail/News client (why not?, it makes "search folders" way simpler)
CD/Book/Whatever catalog
Notetaking applications (KJots, KNotes)
RSS aggregator (try handling 300 feeds in a flat file :-)

Yes, all of these can be implememnted by grepping a few text files.
But

a) That doesn't scale
b) That's ugly ;-)
c) That's actually harder!

Not one? I even mentioned one that does use it in my message :-)

Please ask your VB-programming friends if having a semi-decent DB
available doesn't help writing apps.
