Personally I think the reasons are very simple. ARM is a 32 bit core 
that is exceptionally well supported, ie if you can program a Philips 
ARM7 you can usually program a Samsung ARM7 with little or no effort, 
and usually using the same tools. Not only is it well supported but the 
number of variants available is huge, and the prices are very close to 
those of 8 bit cores, ie you can get 32 style peripherals (complex 
timers, hi res A/D CAN, and all sorts of other built in comms, for about 
the price of a high end 8 bit device. The ONLY drawbacks to ARM7 so far 
that I see are no very small pin count parts, comparatively high current 
consumption, and no real power saving modes. Other than that I don't see 
why you wouldn't choose one over most other micros.

Again most of my work is in very low power designs, so I haven't had 
cause to use one myself yet, but it would currently be my weapon of 
choice where current consumption was NOT an issue and I was starting out 
on a new design. I use the MSP430 family for the vast majority of my 
designs.
