So Microsoft's latest Apple Tax ad actually goes after the iPod and promotes the Zune, which is interesting on a number of levels. The argument? That filling a 120 GB iPod with songs from the iTunes Store would cost about $30,000. Or you could just get a Zune and subscribe to a Zune Pass for $15 a month, which is a little.

While some will argue nonsensically about how you don't "own" subscription music, I'd also point out that that $15 includes 10 free songs each month, which over time, would amount to quite a music collection, presumably of music you tried and then liked so much you decided to buy it. That's a lot better than spending a buck a song, only to later discover your musical tastes have evolved. As they will.

By the way: How long would it take to spend $30,000 on Zune Pass? About 2000 months, or over 166 years. In that amount of time, your musical tastes will surely change several times, too. :) Good thing you didn't waste money buying that music, eh?

Interesting ad.
