Updated October 2026

It also adds 6 GHz Wi-Fi and a wall mount, and works as a kitchen TV and family command center as much as a smart home controller. The Google Nest Hub (2nd Gen) is the small, affordable option: a 7-inch tabletop display in four colors with Google Assistant and no camera, which suits a nightstand or a privacy-minded bedroom. Both have a mic-off switch, a motion sensor, a Thread border router and a Matter bridge, partial Home Assistant support and subscription-gated alerts for glass breaking and smoke or CO alarms. Choose the Amazon Echo Show 21 for a big shared screen in an Alexa home, and the Google Nest Hub (2nd Gen) for a compact Google Home display.

What owners say

Owners of both displays use them for photos, recipes and controlling the home, and both groups bring up camera feeds shown on screen. Amazon Echo Show 21 owners treat it as a kitchen TV as well: they praise a bright screen readable across the room, streaming apps that run without hiccups, shared calendars and widgets for the family and a photo frame that looks like art on the wall. Their complaints are that Alexa+ is still buggy and English-only, that built-in sound is only okay so many add a soundbar, and that updates have broken features. Google Nest Hub (2nd Gen) owners love it as a Google Photos frame and a bedside clock, find its sound surprisingly good for the size and report years of reliable use, while noting it offers less control than the Google Home app and understands only major languages well.
