I’ve read some good and some not good reviews of the Lenovo smart clock. The not good ones point out the obvious limits of it, but I think they miss the point.
To me the main reason you want this smart clock: it can help you get your smartphone out of your bedroom. If you get one of these for the night table near your bed, you get most of the things you want your phone to do: wake you up, play white noise, tell you the temperature before you get dressed. It does all that, while preventing you from doomscrolling or exposing your eyes to light that keeps you up. For those reasons, I think it is a great thing and the main reason you want it.
You can also turn the microphone off if you are concerned about Google listening in on your bedroom (a proper fear). Or if you just don’t want anything “smart” in your bedroom, phone or otherwise, I recommend you check out this beautiful Moon Clock from LL Bean. My grandfather had one of these and it was a beauty.
