Andreas Osthoff | May 2023
"The Asus Zenbook S 13 is the slimmest OLED ultrabook worldwide struggles with annoying fans. The new Zenbook S 13 leaves us with mixed feelings, particularly since last year's model was so good. Asus has completely reworked the device, making the laptop noticeably slimmer. The result also looks good and the case makes a great impression, particularly also in terms of the stability. The new plasma ceramic surface feels great, and there are no problems with fingerprints. In addition, it now includes some of the known connections such as an HDMI port and a regular USB-A connection, which is a good achievement in such a slim device."

Joshua Goldman | April 2017
"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
