i Phone boost to US GDP ???

The Wall Street Journal is running an article where they suggest that sales of the new i Phone could boost US real GDP growth.

But the i Phone is built in China by a Taiwanese based firm.  So the consumer and business spending on the new i Phone will be offset in the GDP accounts by imports of the i Phone, making it a wash in the GDP accounts.

You would think that the Wall Street Journal would know this.   I guess this is just another example of how under the new ownership the low standards of the Wall Street Journal editorial page are spreading into its  news coverage.
