This holiday season, you can count on just about everyone to shop smart, and I mean that in both senses of the phrase. Everybody wants to get the best deals and the most bang for their buck, yes, but I’m also talking about the internet of things, those smart devices of every form and function that currently dominate the holiday catalogs of Walmart, Target, and every other big-box department store. With Amazon launching a whole new line of Alexa products, including a digital assistant for your car, a voice-controlled microwave, and even a “smart plug,” we can now fill our homes with enough gizmos and gadgets that we’re beginning to resemble The Jetsons.
