Externally, there's not much to tell the Google Nest Hub (2nd gen) apart from the original. Design-wise that's not a problem, as this is still one of the best-looking smart displays. Inside, you get the Google Soli motion sensor, which gives you gesture control to manage media playback, and this enables the new Sleep Sensing technology, which will tell you how well you slept. In practice, positioning the display properly can be hard if you don't have the right features, and Sleep Sensing wasn't that useful. For owners of the existing Nest Hub, there's not much reason to upgrade, but if you need a new (or second) smart display, this one is great value and works well.
Good price; Clever motion sensing for gestures; Brilliantly combines voice and touchscreen actions;
