To date, Google has released three Assistant Smart Displays. 9to5Google can now report that the company is working on a new Nest Hub for 2022 with a dockable tablet form factor where the screen detaches from a base/speaker. From the report:
According to a source that has proven familiar with Google’s plans, the next Nest Smart Display will have a removable screen that can be used as a tablet. It attaches to the base/speaker for a more conventional-looking smart home device. This new form factor comes as Google has spent the last few months adding more interface elements to the 2nd-gen Nest Hub and Nest Hub Max. Swiping up from the bottom of the screen reveals a row of “apps” above the settings bar. You can open a fullscreen grid of icons from there. Applications and games on the Nest Hub are essentially web views, so this is technically a launcher for shortcuts.
Speaking of the web, Google also spent the end of last year adding a more feature-rich browser that even features a Gboard-esque keyboard. You can also send sites directly to your phone and enable text-to-speech. Both of these additions can be seen as laying the groundwork for a tablet-like experience, with web browsing obviously being a popular task on big screens. Many questions about the implementation remain unknown, including what OS/experience the undocked tablet will run. Chrome OS is likely too power-hungry (and as such costly) considering the affordability of Nest devices, while Android would open the door to existing apps and the Play Store.
