Yeah, I really overlooked the point that I need to support 1.3. The
reason why I used coredata was that I need to create an application
that requires a lot of storing and retrieving of object in efficient

jsut there and too good to be ignored. I guess I have to find some way
to do it without coredata now.
Why? Unless you need to support existing users, all of the data I've
seen indicates that a Tiger only application would be successful. The
Omni Group's statistics page (http://update.omnigroup.com/) is
particularly useful here. But in general, from everything I've read
from commercial Mac developers, users who would buy your software are
also likely to have bought the latest in Apple software, including
the OS. Of course I don't know the specifics of your application or
the market it targets, but be sure to weigh the effort to redo your
code without Core Data with the possibility of marginal Panther
sales. My knowledge is merely anecdotal, so take it with a grain of
salt.

P.S. Releasing an app that uses Core Data on Tiger and the other code
on Panther would be nice for us Tiger users. :)
