Which smart speaker should I buy? How the Apple HomePod, Amazon Echo and Sonos could improve your life

The most exciting thing about smart speakers is that they are all so utterly imperfect. Each of the mainstream examples – Amazon's Echos, the Google Home, Sonos's wide range and the new Apple HomePod – packs within it stunning technology that would have been unimaginable just a couple of years ago. But they're also full of downsides, making choosing one a matter of deciding what you want, not simply settling on the best. Deciding is a matter of picking which things you want – and which things you definitely don't. Some sound good, but are terrible at talking back to you.
