"Prior to the embedded SBC market coalescing around a handful of PC-compatible standards, it was nearly impossible to locate two SBCs that bore much similarity with to other. The PC architecture brought a degree of order (in several shapes and sizes) to that chaos, by serving as a unifying force -- a situation which persisted for nearly two decades.
"Today, with the established norms disrupted by new interfaces (USB, FireWire, wireless, . . .), architectures (MIPS, PowerPC, ARM, . . .), and operating systems (Linux), the embedded SBC market is entering a new phase of its lifecycle -- one that will initially be characterized by expanding diversity in operating systems, processor platforms, peripheral interfaces, and physical form-factors."
