Google's counterpart to Amazon's Echo. Announced in 2016, Home (later rebranded as Nest) is a virtual assistant and wireless speaker that streams music via YouTube Music (previously Google Play Music). Home can be used to control lights and other household devices and also connect to other Home/Nest speakers in different rooms. Like Amazon's Echo, Home/Nest are stand-alone devices and one of the first Google products to use Google Assistant. See Amazon Echo

Home Mini (Nest Mini) and Home Max (Nest Audio)
In 2017, Google introduced a smaller Home Mini (rebranded Nest Mini) and a larger Home Max (rebranded Nest Audio). All models have the same features as the original Home with the primary difference being sound quality.
Home Hub (Nest Hub, Nest Hub Max) Smart Display
In 2018, a 7" Home Hub was added with smart home control. Rebranded as Nest Hub in 2019, a larger Nest Hub Max debuted the same year with a camera for video calls. Hub models can also display a clock or photo slide show. The Hub groups all connected audio and smart devices for centralized control of the home, and users can view the scene from a doorbell camera.

The Original Google Home
The Home sits almost anywhere in the room, but does require AC power. Although the original Home offered decent sound quality, the smaller Mini and larger Max offer more choices.
Lenovo Smart Display
Based on Google Assistant and the Google Home app, Lenovo's Smart Display, which has an 8" or 10" screen, is used for getting answers, watching videos, video calling and smart home control. Like Google Home, "Hey Google" wakes the unit. (Image courtesy of Lenovo, www.lenovo.com)
