Here’s a hard truth: Even if Apple decided to carve its new Nano out of petrified poo and bless it with a Braille display, the interface alone would still make Cupertino’s latest flash-based music player leagues better than the competition. So what’s our opinion of the new Nano? Well, it’s just like the old Nano, just a little roomier (fine) and shaped like an airfoil (weird). This new aerodynamic form doesn’t seem to have any discernible functional purpose, but the Triscuit-shaped Nano had some distinct advantages over this new 4th gen model: It was a better piece of fitness gear, fitting more comfortably into sporty armbands and the tiny pockets so common to the backs of running shorts. The old screen orientation also allowed you to control video content more intuitively, though the new elongated shape is better for navigating long playlists. Sure, that’s a decent upgrade-as is the price-to-gig ratio-but unless you absolutely need to shake-to-shuffle (spazz) or will be building an airplane out of iPods (paging Mr. Branson), the best thing about the new Nano is how flooded eBay’s gonna be with cast-off 3rd gen models.
