The Pixel C sports a 10.2-inch screen, which is smaller than competing laptop/tablet hybrids. But it makes it a really nice size for, say, using it on an airplane's tray table, as I did here.
The Tensor G6 on that Pixel Tablet will have a second USB-C controller for “tablet only use cases.” It will support USB 3.2 and DisplayPort output with daisy-chaining allowing a second display.
