Interesting piece I ran across this morning:
Ultra-Low-Power Cell Phones
Programmable analog circuits could drastically reduce the power needs and cost of electronics in portable devices.
A radical approach to making the electronics in cell phones could cut the power consumption of cell phones anywhere from 10 to 100 times, while also dramatically reducing the size and cost.
