The Contiki team has just released version 2.1 of the open source Contiki operating
system for low-power, wireless, memory-constrained networked
embedded devices that typically have as little a few kilobytes of
RAM. The major highlight of this release is a unique energy
profiling mechanism that measures where energy is spent, and how
much energy that is consumed. This is extremely important when
optimizing for low-power operation: to know where to optimize, one
must first know where energy is spent. Other additions to the 2.1
release are low-power radio protocols that increase system lifetime
from days to years, and improved data collection routing protocols.

I'm probably never going to use it myself, but it's very interesting after reading more about it.
It's fascinating to see how much usability you can still get out of very old machines (Apple II, Z80, C64,...), if they are only programmed accordingly.
And if you take a look at the power consumption of these TI-microcontrollers, (I think) you could run them literally for years with off-the-shelf batteries, makes up for some interesting applications.
