I'm sure by now you're all-too-familiar with the annual mobile device product line refresh. Every fall we get updated versions of the now ubiquitous mobile devices. Apple, Amazon, Google, and others all push out slightly updated hardware just in time for the holiday shopping season. This year's upgrades are almost all incremental. If you already own a 2012 device, you should feel comfortable hanging on to it. Users looking to upgrade from models that are two or more years old or shoppers new to mobile devices have good reason to be excited.
