Just remember that ARM cores in micros cover a VAST range. ARM7tdmi
cores can be very low power, as can some ARM9's, but not all. ARM11's
of course are a bit on the hungry side, but then they start to rival
Pentiums in capacity.

ARM-Cortex (A8, A3, M0, M1, M3) all have specific feature mixes. The
PIC32 at the moment, with no Ethernet or CAN interfaces probably
compares with low end ARM7tdmi based products and is comparable in
power consumption.

AVR32UC3A and AVR32UC3B are comparable in cost to PIC32's in volume.
