I'm no Apple fan, but I applaud them on this. I would guess that if there were an option with a cost difference were on the order of $10-25, many consumers would pick the "assembled in USA" option ($50+, probably not?). With the right kind of marketing campaign and public pressure, I would imagine that businesses would pick this option either as a marketing strategy, due to public pressure (guilt?), genuine interest in the US economy, or some combination of those?

I always look for made in USA and it gives me more confidence.
