You know what's annoying? Having to get up and walk all the way to your iPod dock to pick a song. Sure, there's the good old remote control these days, but you'd still need to squint at the tiny screen from afar if you want any modicum of song control. The couch potatoes at Cignias Inc. probably felt the same pain and thus came up with the free MusicNAO app for the iPhone, iPod Touch and BlackBerry, allowing you to control and browse content over WiFi on the iPod docked on NAO Symphony speakers. It doesn't end there: you can also stream music from the latest iPhone OS
