While it's certainly true that android is happy to run on mips, there is currently a Renaissance of arm-based SOCs with interesting silicon coming from freescale, ti, marvell, phillips, qualcom, and samsung to name just a few. Most of these have thier own combination of differentiators like video codecs, signal processing cores, and analog interfaces. I see mips running mostly in set top boxes that use the discreet codec/drm devices and routers with external 802.11 radios and switches, and some network-centric processors... but there doesn't seem to be nearly the level of diversity present in the arm ecosystem lately. I hope that android's architecture agnosticism allows more payoff on investments in other interesting architectures like mips, sh, and openrisc.
