The comments raise one obvious question—why isn’t Siri Wozniak’s preferred voice platform? He does mention Apple’s (APPL) smartphone voice assistant, along with similar services. But his greatest praise goes to Amazon’s (AMZN) device, as he rattles off an evocative list of products and services—Uber, pizza, and paper towels—that he can access through the small speaker hub.

The Echo’s appeal, for Wozniak and the average consumer, may have more to do with what it’s not than what it is.

And while it can do a lot of practical things, the Echo is strongly oriented towards music and relaxation, rather than being a work tool. (I personally love that my Echo easily recognizes the names of even obscure musicians.) In Wozniak’s words, everything about using the Echo gives a sense of “luxury and freedom.”
