I've experienced this first hand, and it's extremely frustrating. For some reason, my Android app apparently refuses to start on the Droid X, despite it working fine on my Nexus One, as well as the emulator with the correct screen size and the correct version of Android OS (or at least the base version of the OS, before carrier customization). I can't justify buying more than one Android phone. The Apple store's approval process is infuriatingly slow, but I've never had any device model compatibility issues. I'll take slow approvals any day.
