The ZenBook Duo UX481FL is a mixed bag. One one hand you're drawn in by the dual-screen form factor, but its major selling points are actually the large battery, the smooth performance and thermals, the good quality panels and the capable speakers.
nicely designed and built; fair quality IPS screens; both of them; solid performance even with out-of-the-box settings; runs cool and quiet with daily use and demanding loads; excellent battery life; fair speakers
limited ergonomics and portability; cramped keyboard and minuscule clickpad; no Thunderbolt 3; full-size card-reader or USB-C charging; a step back from the previous ZenBook Pro UX480 in terms of performance; hot air blown straight into the matte screen
