*cough* There really isn't a good argument in general for abstracting
out database access to support multiple platforms.
The only argument I ever see is:
We want our product to support as many databases as possible. Which is
certainly a valid business argument but certainly not a good technical
argument.

I am not sure why you would be offended by another's experience. I am
offended that you are offended that he wasn't offended. Good lord, take
a breath.
I would agree that in my experience most applications that choose to
abstract their database usage generally make bad choices in how they do
it and thus have a negative impact on not only the survivability of
existing code but the maintainability of said code.
Are their apps out there that do it right? Oh probably, I have never
seen one though.

useful not always == good.
Windows is useful.
Windows is not good.
