How could the secondary screen of a tablet help the user? It may be used to access apps more quickly with its shortcuts. As per the images shared, Lenovo will include a stylus with the product which could come in use on the secondary screen too. Since it is a 17-inch notebook, Lenovo might just be able to fit in an 8-10 inch secondary display on the chassis, considering the images shown are not going to be exactly similar to the actual product, if Lenovo is planning on getting one out in the markets.
As for connectivity, the laptop is shown to come with two USB-C ports, two USB-A ports, one HDMI port and a 3.5mm headphone jack. The laptop could also feature Harman Kardon speakers.
There has been no official word from Lenovo about the unique laptop. Rumours suggest that the company might unveil it during CES 2022.
