Our Verdict
Lenovo IdeaPad Flex 5 14 (2020)
Lenovo Chromebook Duet 5 (2021)
The Lenovo Chromebook Duet 5 (2021) and the Lenovo IdeaPad Flex 5 14 (2020) are very different. Although they're both 2-in-1 convertibles, the Duet 5 is a Chrome OS tablet with a kickstand and detachable keyboard, while the Flex 5 is a Windows clamshell laptop with a 360-degree hinge. The Flex 5 is better for productivity as its CPU can handle heavier workloads, and it provides a better user experience, like a better keyboard, touchpad, and port selection. However, the Duet 5 is better for media consumption because it has an OLED panel with superior image quality.
