Our Verdict
ASUS Chromebook Vibe CX34 Flip (2023)
Lenovo Chromebook Duet Gen 9 11 (2024)
While the Lenovo Chromebook Duet Gen 9 11 (2024) and the ASUS Chromebook Vibe CX34 Flip (2023) are both 2-in-1 Chrome OS devices, the former is a tablet with a detachable keyboard, while the latter is a clamshell model with 360-degree hinges. The Lenovo is a better choice if you primarily use the device as a media consumption tablet because you can detach the keyboard to make the device easier to hold. However, the ASUS is more ideal for productivity because its larger screen, more spacious keyboard, and larger touchpad make it feel much more comfortable to work on. You also get more ports and better performance on the ASUS.
