That's a mild understatement. ARM practically owns the entirety of the mobile device market. Every major mobile OS is near-exclusive ARM based (Android being a very recent exception, and Intel handsets haven't shipped yet) Outside of China (where MIPS seems to have a bit of marketshare); you'd be hard-pressed to open up a reasonably smart non-PC device and /not/ find an ARM chip.
