The Lenovo Smart Display will have an 8- or 10-inch screen for $200 or $250, respectively. Both will go on sale this summer, but no word if they'll be available overseas. The US price converts to roughly £150/AU$250 and £180/AU$315.
Like an Amazon Echo Show, the screen will display info relevant to your questions. You can also watch videos and the news on the screen. You'll primarily control it with your voice. Give a command, and you can control your smart home, add an entry to your calendar, search the web and more.
