The worst problem about running power directly from the car's supply is
that it's not a clean, steady stream of juice. Computers run best on clean
power, and a car's power is anything but. Hence, the deal of being grossly
inefficient in changing 12V-->120V-->12/5V is true, but if you're using an
inverter + UPS or some such, you get the benefit of the cleaning up of that
power supply.

Now, granted, with all my electronics around my apartment (25-30 computers
+ audio + phone), no doubt my power is less than clean, not to say anything
about transmission rates for my ethernet or the cancer I'm getting from the
EMF radiation. :)
