Cortana gets no respect. Microsoft’s smart assistant is actually pretty solid, all things told, but it rarely gets mentioned in the same breath as Alexa, Siri or Google Assistant. Maybe it’s a problem of marketing —the company was quick to point at Build in May that its smart assistant now has 141 million monthly users. More likely though, it’s a problem with Microsoft’s hardware strategy.

The company knew as well as the rest of us that CES 2018 was going to be a smart assistant battleground, but Cortana barely entered into the conversation. Google’s Assistant dominated the show’s headlines through sheer brute force of product announced and an over the top ad campaign that found everything from the monorails to the signage at the Westgate emblazoned with the words “Hello Google.”
