Innovation is always important. The iPhone was innovative. iOS was innovative. Without those two, we wouldn't be having this discussion. We would still be using Nokias and Blackberries, or Android phones which would be like Blackberries -- not the iPhone.

As far as paying for R&D goes, how much does it take to replicate something? I'd say a fraction of the cost since you already have the product in front of you. All you need to do is duplicate it.
