The Zune Cometh
Saying that a new iPod is coming out is somewhat of a double-edged sword. It might hurt iPod sales in the present, but if that new iPod does come out, it will only help Apple and hurt Zune sales. In the long term, probably not a good strategy. Short term? Might work. Might not.
The use of such a stupid strategy also highlights the stupidity of Zune marketing: it bashes Apple instead of hyping how good its own product is. Does that say something about how (un)good the Zune is going to end up being?
