From a RISC OS community site Drobe Launchpad, similar to morphzone comes this article that compares the market for RISC OS systems to the Amiga & Pegasos market.
It largely focuses on AmigaOne and OS4, but fairly mentions the Pegasos and MorphOS:
The RISC OS development split and competition from emulators is not so different from the emerging AmigaOS clones: Pegasos is another motherboard powered by a PPC processor that runs MorphOS, an AmigaOS clone with 68K emulation support. There's also the popular UAE, an Amiga emulator for PCs, and AROS, an open source clone of AmigaOS.
