I guarantee if they broke their focus groups down by state or even coast, you would see a huge disparity between west coast opinions vs. everyone else. It's interesting demographically but ultimately focus groups offer nothing to anyone with real focus.
Except you can focus your advertisements regionally and not come off looking smug in one part of the country and heros in another...
It would probably be wise to center a commercial around a very small town in Indiana where kids are playing baseball and a young farmer is checking weather or something and play those ads in areas where those viewers can relate and react emotionally to it.
For example, I'm not reacting positively to those Microsoft Surface ads with hipsters dancing in a park or board room. I'm a 36 yr old dad of 3 (soon 4) who doesn't exactly connect to dub stepping with a computer....
Apple should focus their marketing on segments within their target rather than try to make sweeping ads that many segments will perceive in a way other than they intended.
