MacOS Computers
These are mainly measured figures on some of the Macs we've owned, plus a few submitted by friends.
Macs are generally better on power than equivalent PCs. This is mainly due to the much lower power consumption of the processor itself. PowerPC processors use anywhere from 10 to 20% of their Pentium equivalents. Apple also seems to be more concerned with power consumption than many PC vendors. Flat panel iMacs have very low consumption because of their LCD screens.

Notes
Consumption figures for sleep mode vary significantly with the operating system version. The later versions of OS 9 were excellent, whilst early versions of OS X were poor. The current version of X - 10.3.x is probably at least as good as, if not better than, the old MacOS.
