Microsoft Targets iTunes Prices in New Zune Pass Commercial
Ars Technica presents an analysis of the numbers and describes how Microsoft neglects to mention the differences between "owning" and "renting" music.
Of course, it's not exactly $15 versus $30,000. The $15 is a monthly fee, so you're likely going to be paying more if you plan on playing music for more than a month. That said, it would take you 166 years and 8 months to shell out $30,000 for the Zune Pass; many of us won't be living that long.
As of November 2008, the Zune Pass allows its users to keep any 10 songs per month. In other words, if you wanted 30,000 songs for keeps, just like the iTunes Store, you would have to wait 250 years. The cost would be a whopping $45,000, however. In other words, it's only really worth it if you're OK with the fact that you have to keep paying the monthly fee to keep access to the songs that you don't yet own. Otherwise, iTunes (or any other la carte model) is the way to go.
Price comparisons between Microsoft/PCs and Apple have been a focal point of recent Microsoft ad campaigns, beginning in earnest about six weeks ago with the launch of the "Laptop Hunters" series of TV commercials, as well as associated Web advertising.
