Your basic argument is sound but your numbers are a little off.
While a computer may have a 150 or 300 watt power supply it's
unlikely it will actually be using that much. A IIci is a better
choice as a router and it's power consumption is more like 60-70
watts (going from memory, I don't have the numbers here). This is
assuming any monitor is turned off in normal use. Your wall wart on
the other hand will be probably be using more power. While it's
likely to be using somewhere around 700mA (5.25 Watts) the power
supply will waste that much again so the real power will be closer to
10.5 Watts.
