I was at the Apple store today and I noticed on the 12" PowerBook, I went into the Energy Saver Preferences. I noticed under Processor Performance, there were 3 settings, Highest, Reduced and Automatic. I'm sitting here at my 12" (Rev A) and I notice I don't have the 3rd setting: automatic. Is this a feature of the 12" Rev B, or am I missing something? Again, I have a 12" 867 MHz and I just upgraded to 10.3.3 from 10.3.1. Any thoughts?
