I haven't had any device-specific error reports for the few Android apps that I have worked on, but they are pretty vanilla.
There are occasionally comments in the android-developers group about issues specific to particular phones. Seems like the Droid is often mentioned, and the thread I recall was with the camera.
I imagine it would be frustrating to get a crash report, not be able to duplicate it, and have your app work fine on the dev phone in your possession.
