+1 point for the EVO.
Droid X, menu, settings, sound has silent mode, vibrate, volume, incoming calls ringtone, notifications ringtone (can't choose seperate ringtones for different notifications

), feedback, and smart sensors.
Droid X, menu, settings, display only has brightness, rotate, animation, timeout, wallpaper, and roaming banner. Nothing for notifications.
I could have sworn that when I first got this thing, I could at least set different ringtones for different types of notifications, but I can't remember for sure, but now I can't. Maybe an update took that away.
Maybe EVO does, but Droid X doesn't.
