Conclusie - Indrukwekkende Asus ExpertBook B9 ondanks enkele kleine zwaktes
Dit is de verkorte versie van het originele artikel. Het volledige, Engelse testrapport vind je hier.
Onze review van de Asus ExpertBook B9450FA brengt heel wat uitstekende features aan het licht. De notebook is erg licht en draagbaar met een extreem lange batterijduur. Het toestel biedt voldoende helderheid en goede kleuren en prestaties voor een dergelijke notebook. Functies zoals een manuele sluiter voor de webcam en een numeriek toetsenblok dat op het clickpad wordt geprojecteerd, maken het aanbod compleet.
De Asus ExpertBook B9 is een ultralichte notebook van hoge kwaliteit met een uitstekende batterijduur.
We hebben echter een paar punten van kritiek die voor sommige potentiële kopers doorslaggevend kunnen zijn. Asus heeft ervoor gekozen geen SD-kaartlezer te integreren en we hadden gehoopt op een WWAN-optie voor een toestel dat zo draagbaar is als dit. Het feit dat de RAM-module is gesoldeerd is niet geweldig, maar dit kan op zijn minst worden gerechtvaardigd door het ultradunne profiel van het apparaat. Er zijn in ieder geval twee SSD-sleuven beschikbaar die gemakkelijk toegankelijk zijn omdat de klep aan de onderkant gemakkelijk te verwijderen is.
