Lightweight 2-in-1 laptops with 13.3-inch or 14-inch screens are widely available, with Dell and Lenovo, in particular, offering some compelling models.

The footprint is relatively tidy at 299mm by 209mm, but the laptop is rather thick at 18.79mm. On the upside, this does allow the device to accommodate relatively sizeable VGA and Ethernet ports in the
