A good indicator is to take your Zune domain and replace the word Zune with iPod. In your case ipodgadgets leads to a godaddy parked page. This domains owner has had 5-6 years to develop and hasn't done so. Who knows how much he/she is raking in a month but I'd venture to say it is less than $25.
I would like to think that Zune will overpower the aging iPod but it is too early to tell.
