Sadly, these commercials will work for the same reasons that mac ads have - they pander to the uninformed (or those that are informed from second-hand knowledge). The kinds of people that believe everything they hear. ie "macs don't run any programs" "pcs crash a lot" "macs are overpriced" "pcs are confusing" etc etc
Just incase it comes up, I own a macbook pro, used to an ibook g4 AND g3, have appletv, an iphone, etc etc so i am an apple guy and would only buy their products. I just think these ads will be/are effective.
