The larger screen not only facilitates viewing video and still images, but it also accommodates the Apple's refreshed iPod interface. This new interface, found on both the Nano and the Classic (the latter is now the moniker for the full-size, video-capable iPod), is less of wholesale change than it is a facelift. The interface update consists of two primary components: The introduction of Cover Flow for visually navigating through your album collection; and the repurposing of the white space on the right-hand side of the screen to introduce visual content previews.
Let's explore that last change first. As you move through the Nano's main menu, the options look pretty fairly familiar: Music, Videos, Photos, Podcasts, Extras, Settings, Shuffle songs. But instead of a plain white screen at right, the right half of the screen gives you a preview of your menu selection--an appealing substitution for what was once just unnecessary, bright white space. Of course, this makes album art all the more important--at least once, I had to shudder as a distasteful album cover floated by--who knew? I choose music based on my eclectic musical tastes, not on the album cover art. Nonetheless, I applaud Apple for the extra visual sense that the floating previews add to what otherwise remain straightforward, intuitive text-heavy menus.
Well, straightforward with one notable exception: Cover Flow. First introduced as a means of navigating your album collection in iTunes, Cover Flow's introduction has long been anticipated in the iPod--especially after seeing it introduced in Apple's iPhone earlier this year. And it doesn't disappoint: Cover Flow, the top navigation option under the Music menu, offers a completely different visual navigation experience.
