Index Cards is a nice app, one I've admired without using it much. As you say, once Scrivener for iPad comes out, there may be no reason to use this app at all.

If I were the developer, I'd think seriously about repurposing it. That is, making it useful for more than writing stories. It could easily be converted to a handy information manager by adding some meta-data capability, such as dates and times, tags. Add due dates with iOS reminder integration. Set it up for different card types:

- Note
- Contact
- Event
- Task

With different meta-data fields for each. Something like that, anyway.
