Our Verdict
Lenovo Chromebook Flex 5 (2020)
Lenovo Chromebook Duet 5 (2021)
The Lenovo Chromebook Duet 5 (2021) and the Lenovo Chromebook Flex 5 (2020) are both 2-in-1 convertible Chrome OS devices. However, the Duet 5 is a tablet with a kickstand and detachable keyboard, while the Flex 5 is a more traditional clamshell laptop with a 360-degree hinge. The Duet 5 has a brighter and more colorful OLED panel, and its SoC performs better overall while being more power-efficient, resulting in longer battery life. On the other hand, the Flex 5 has a more comfortable keyboard, a larger and more responsive touchpad, and a wider port selection.
