One example: RIM wants to ship their Playbook with support for Android apps. They probably need the Android source code in order to do this. They've annouced that Playbook will only support Gingerbread Android apps. With the Honeycomb source code they might be able to support apps that work better on tablets.
It seems to me however as an Android watcher, that when Google developed Honeycomb in parallel to Gingerbread, they created an internal fork of Android to specifically support tablets.
What needs to be done and it seems what they intend to do is heal the fork, so they have a single codebase again. The real issue is whether they manage to do that in time for Ice Cream.
