The use of a full HD IPS panel delivers sharp visuals with good color accuracy and wide viewing angles. Its durable magnesium alloy chassis gives it better resistance to physical wear and tear compared to typical plastic alternatives.

Lastly, the laptop's fan noise and heat output are relatively low contributing to a quiet and comfortable working environment.

Despite its portability, the LG Gram 15Z90R-Q.APB3U1 sacrifices some connectivity options, lacking an Ethernet port which may inconvenience some enterprise users. The absence of a keyboard backlight limits usability in low-light conditions. Its integrated Intel HD Graphics 620 GPU restricts the laptop's capability for gaming or intensive graphical work. Performance with only 8GB RAM might be limiting for power users running multiple heavy applications simultaneously. The screen, while good for general use, does not support touchscreen input nor higher resolutions such as 4K. Additionally, repairability and upgrade options are limited due to the compact build and soldered components in the system.
