Apple didn’t invent the digital music player, but when was the last time you saw someone listening to MP3s on something other than an iPod? Still, gone are the days when the original iPod’s 1,000-song capacity could wow music fans. In the age of ubiquitous network connectivity, we want everything, all the time. And now that Apple has ironed the kinks out of storing music online, the next logical evolution of the iPod is that it gets smaller and more connected. And by small, we mean small. In fact, the iPod of 2015-or iPod Air, as we like to call it -- could be called the “iPod-less iPod.”
