Asus advertises the quad-array microphone as one of the main features of the ExpertBook, which costs upwards of 2000 Euros (~$2400). It is supposed to improve the video-conferencing experience. At the same time, Asus uses the same 720p web camera as in almost all other current laptops such as the 3000-Euro (~$3600) MacBook Pro. When most people have to use their web camera everyday to study or work from home, this has to change!
