radar', with dominating a sector.
Some are more significant than others though... MIPS for example joined the MCU game only recently, and they have (like PPC) major codesize issues, so you need a bigger and more expensive device.

Sure power consumption matters. But it's nothing new though - ARM wouldn't be where it is today if it hadn't been low power from the start. The core matters a lot of course as it uses much of the power. Intel have recently found out again how bad CISC is for power with their Atom core (one can run an ARM at full speed on the power it wastes when it is in its deepest sleep!). Having good process technology helps, but it doesn't "fix" a bad core.
Well that's their claim anyway... Could you point me to just one device that is actually pin compatible? A look at the ST/FS websites doesn't prove there exist any identical devices. The only thing they have in common is the e200 core, that's about it. As I've said before, making identical devices in every aspect doesn't make any commercial sense.
