x86 Uncommon in Embedded systems?

Although the 8086 was primarily developed for embedded systems and small single-user computers, largely as a response to the successful 8080-compatible Zilog Z80, the x86 line soon grew in features and processing power. Today, x86 is ubiquitous in both stationary and portable personal computers and has replaced midrange computers and RISC-based processors in a majority of servers and workstations as well. A large amount of software, including operating systems (OSs) such as DOS, Windows, Linux, BSD, Solaris, and Mac OS X supports x86-based hardware.
