Don't think of Amazon Echo as a speaker. Think of it as a Trojan horse

Stephanie Palermo wasn't interested in living in a "smart home" outfitted with web-connected appliances controlled remotely by phone or computer. She didn't need her fridge to have Wi-Fi or her blinds to close themselves. But when Amazon temporarily discounted the price on its voice-controlled Echo speaker to 99 for Amazon Prime members, there was "a low barrier to entry," and the 28-year-old from Belmont, Calif., was willing to take a risk. She started using the cylindrical device as a hands-free speaker. During board game nights, she'd tell Alexa -- the artificial intelligence that powers the Echo -- to play themed music from Pandora.
