Apple has just revealed its 6th generation iPod nano, which has been outfitted with just about the boldest redesign the portable media player has experienced yet. Gone is the clickwheel, to be replaced with a touchscreen interface and a shuffle-esque square form factor. It’s now 46 percent smaller and 42 percent lighter. Hard volume buttons on the side and a clip on the back provide the minimal hardware accouterments to that multitouch touchscreen, while the inside provides enough juice for 24 hours of audio playback. Seven total color variants will be up for grabs, including a Product RED option, with prices set at $149 for 8GB of storage or $179 for 16GB and pre-orders being taken today.
