The article refers to one device from Apple vs tens from Samsung. I think it would be fairer to compare with one device, such as their most popular one.
Unfair would be to compare the number of macs sold vs. the number of android phones sold since those devices don't compete against each other on the same market.
Edit: My view may be too US based, but the 3GS costs nothing after carrier subsidy.
Edit: Response to the parents edit: Yes, your view is US-based. If I buy a phone and get a phone contract without subsidy, my contract is cheaper - up to 10 euros/month. I'd be surprised if that's much different in the US - you always pay for the subsidy in one way or another.
Or we could compare the end results of two different business strategies.
