Pros
- Very long runtime in review testing: 22 hours 2 minutes of looped 180-nit video playback on the 54 Wh battery in the lowest-power mode
- Geekbench 6 of 2421 single-core and 11348 multi-core in review testing, with multi-core ahead of the Core Ultra 7 258V and Ryzen 7 PRO 7840U laptops it was compared against
- Aluminum chassis (50% recycled and 100% low-carbon aluminum) at 1.53 kg, with two USB4 ports (DisplayPort 2.1, Power Delivery), a USB-A port, a microSD slot and Wi-Fi 7
- FHD IR camera with a physical privacy shutter, plus an optional fingerprint reader
Cons
- The 1920x1200 panel is rated at 300 nits and reached about 326 nits with only about 50% sRGB coverage in review testing
- Windows on Arm: some apps and games run poorly or not at all, and the Adreno X1-45 graphics are weak for gaming
- Only one USB-A port and no HDMI or Ethernet, so adapters or a dock are needed
- RAM is soldered and tops out at 16 GB
