Bugs when first used.
The ZenBook duo is very practical thanks to its dual screen. There's nothing to complain about in terms of hardware.
However, numerous crashes and blue screens occurred from the very first use and even before any software was installed. Analysis via MyAsus did not reveal any problems. Only a Bios update after two weeks of fruitless searching resolved these repeated crashes. It's a shame to encounter this type of mishap. It would appear that this laptop was incorrectly checked after its software configuration.
