Time changes everything. I recall a FedEx arriving at the hotel I was staying at in Los Angeles (for PDC 2005) two years ago, containing a gift from Apple: The first generation iPod nano (see my review), which, at the time, represented the then-current high water mark for portable audio. The 2006 iPod nano (see my review) was even better, though it utilized the same basic form factor. I awarded it a rare 5/5 stars, declaring it "the best small-sized portable media player on the market." This year, Apple updated the nano in more dramatic fashion with a third generation device that includes a number of questionable changes (see my review). However, I still awarded that device a solid 5/5 stars, because none of these unnecessary changes--CoverFlow and the weird "Halfie" UI among the most obvious--demonstrably changed the nano value equation.
