Lenovo's Smart Display with Google Assistant has hit the market. There are two versions of the device, one with an 8-inch full HD screen and the other with a 10-inch full HD screen, priced at $200 and $250 respectively. "The cost is significantly below an iPad mini and it offers far more functionality than just a digital picture frame or a Bluetooth speaker," said Alan Lepofsky, principal analyst at Constellation Research. Buyers will get three months' free access to YouTube Premium. The Lenovo Smart Display runs on Google's Android Things OS.
