Fujitsu used SPARC for everything from servers to embedded systems like cameras for a long time. Another reason is that most of the SPARC ecosystem was built around Solaris, rather than Linux, and the failure of Sun to survive and the replacement of Solaris by Linux based systems vendors took SPARC down with it.
