ASUS Zenbook S14 UX5406SA-PZ658WS
A 14-inch Copilot+ ultrabook built around Intel Lunar Lake — exceptionally thin at under 1.3 cm and light at 1.2 kg — paired with a 3K OLED touch display that sets the visual benchmark for this class. The 16 GB RAM ceiling and absence of an SD card slot are genuine trade-offs, but for travel-first users who want a stunning display and near-silent everyday operation, this is the one to beat.
