I not only agree that banning questions on Web Apps or Web Services is short sighted but the description for smartphones is lacking as well.  My android phones are mini-computers that have an OS, a Keyboard, a Screen, memory and storage.  Questions about software running on those should be valid whether they are connecting to a PC or not.

These two branches of exclusion really are blocking of a large field of view of related technical questions that could be filled by superuser.
