This is the fourth part in our seven-week series of 7for7, seven reasons to wait for Windows Phone 7 debuting later this Fall.

Apple’s got iTunes, Google’s got Amazon, and Microsoft’s got Zune… and if you’re reading this then chances are so do you! You’re probably thinking about ditching your Zune device, though, after you pick up a shiny, new Windows Phone 7 mobile device handset cellphone (running joke if you listen to the Zunited Podcast).
Let me put it this way: if you have already chosen a Zune instead of an iPod, then you most likely agree that Zune is better than iPod and therefore the Zune experience on Windows Phone 7 will be better than the iPod experience is on an iPhone. Right? Right!
But Zune (like iPod) is more than just the device itself (which we know will be amazing), it’s service and community as well. And with Zune, unlike Amazon and iTunes, the clearest advantage is Zune Pass. Since every WP7 device will technically be a Zune, the Zune Pass is very much a feature in its favor. Everyone agrees, Zune Pass is perhaps the best music subscription service available–$15 a month and you get to keep 10 songs each month forever. Financially? Well, let Wes Moss tell you all about that.
Okay, those videos might be obnoxious, but Wes has a point: an 8gb phone would cost $1,980 to fill a $1/song, which would take 11 years to pay if you had a Zune Pass. But that’s not all, there are several great factors to Zune Pass including streaming from the Zune Marketplace, being able to download a song without thinking about not being able to get your money back, and even downloading entire albums to see which song’s good.
Clearly there are more pros to Zune than just the Zune Pass, like its interface and fantastic reputation for recommendations.
If you’re looking for a bit more flair for your rocking out and prefer to synchronize your tunes with more than just computers, Zune is an excellent choice that bridges a beautiful aesthetic with excellent, recommendation-based functionality…

It goes beyond that, though. In short: while Zune may not be fully-customizable (although there are simple hacks out there), the look and feel can be changed; the Zune Social; small features like your purchasing and Zune Pass history help a great deal when having to re-download songs, wireless syncing, album information look-up… all of this, of course, if you like a closed ecosystem more than an open one like Amazon’s MP3 store; Xbox integration which we’ll talk about a little later on in the month; and of course, with video options as well, even though they could be a lot better. Zune’s all about music and music discovery, though.
In fact, we only have one real caveat: Microsoft Points, which is rumored to be going away slowly.
