There may not be much Apple can do to improve on its sixth-gen iPod nano, but we have a few ideas.
Stocks of the iPod nano appear to be dwindling at retailers across the country, suggesting that Apple is planning to update the tiny music player soon. 9to5Mac spotted shortages at Amazon, Target, Walmart, and Best Buy—a common indicator that a product is about to be refreshed by Apple.
The sixth-generation iPod nano was released in 2010, a radical departure from previous nanos. Not much larger than the iPod shuffle, the sixth-gen nano is dominated by a small square touchscreen with limited multitouch abilities. Though it includes an iOS-like interface, it still runs the same Pixo OS that powered previous nanos as well as the iPod classic.
Apple didn't bother updating the nano (or really, any iPods) in 2011 aside from a slight price drop and a few software changes, such as the addition of a Nike+ fitness app. But the short supply of the current nano suggests Apple may have something more in store this year.
