It is a testament to miniaturization that we can now fit an entire entertainment system onto devices no larger than flash drives. Streaming dongles plug into your HDTV’s HDMI port and play content over WiFi. Dongles offer some great entertainment options for those on or off a budget.
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.
Updated November 2013: After a year of living with much of this tech, I have some new insights that should help you decide if you want to settle for slightly older hardware at cheaper prices when shopping for the 2013 holiday season. I have also provided links to the updated versions of the devices that were listed in 2012 as alternatives to the standard Apple/Amazon/Google/B&N devices.
