Dynabook's Portégé laptops seek to offer a blend of light weight, robust build and good performance. The last Portégé I looked at, the 13.3-inch convertible Portégé X30W-J10C ticked a lot of boxes, notably with its sub-1kg weight and all-day battery life. The Portégé X40-J-11C has a larger (14-inch) screen and is not convertible, but like the X30W, runs on 11th generation Intel Core processors and offers Thunderbolt 4 connectivity.
