For every instruction in the original NewtonOS, Einstein runs about 200 to 300 \
instructions on the host machine, needing about 200 to 300 times as much power. Then \
again, during sleep cycles (and NewtonOS makes great use of all kinds of power naps \
and sleep cycles), the emulator is smart enough to let the host system sleep as well. \


So as long as you do simple stuff (like viewing the calendar), battery usage should \
be reasonable. If you use the CPU a lot (hand-writing a novel), the impact will be \
                quite big.
