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."

"The 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."
