Pros
- All-metal three-part body at 1.28 kg and 14.9-16.9 mm thick, tested to selected MIL-STD-810H methods
- ASUS rates the 50 Wh battery at up to 30 hours of video playback and says the 68W USB-C adapter charges it to 60% in 49 minutes
- Full port selection: two 10Gbps USB-C ports with display and power delivery, two USB-A ports, HDMI 2.1 and a headphone jack
- FHD camera with IR for Windows Hello face login, plus a Microsoft Pluton security processor and firmware TPM
- 45 TOPS Hexagon NPU for Copilot+ PC features
Cons
- The US base model's IPS-level panel runs at 60 Hz, is rated at 300 nits and covers only 45% NTSC
- The 8 GB configuration uses soldered LPDDR5X with an 8 GB maximum, so memory cannot be upgraded
- Windows on Arm: apps built for x86 run through emulation
- USB-C ports are 10Gbps USB 3.2 rather than USB4, and Wi-Fi is 6E rather than Wi-Fi 7
