The flaw does not end with "right price". If you look at the sub number to price there is no linear correlation at all! Just the most common sense understanding of this would show that the price of the stock could not even go down since subs at this point are always increasing. It's just bias number juggling that is laughable.
Motley Fool had a good analysis that reinforced the fact that by 2006 just on the basis of the customers that Howard Stern should bring in, Siri should do all right. In addition, there is the MSFT deal that was received with must fanfare but not as much discussion lately.....btw when is the next quarterly report?
