Our Verdict
Acer Chromebook Spin 311 (2021)
Lenovo Chromebook Flex 5 (2020)
The Lenovo Chromebook Flex 5 (2020) and the Acer Chromebook Spin 311 (2021) are 2-in-1 devices with 360-degree hinges that run Chrome OS. The Acer is better for school and multimedia use, with a much lighter frame and a significantly longer-lasting battery. Also, its speakers sound much better, it doesn't get nearly as hot, and it stays completely silent under load. On the other hand, the Lenovo is better for business use, as it has an extra USB-C port, a sharper screen, and a much better-quality webcam and microphone. Also, you can get it with a much faster and more responsive Intel Core i3 CPU, but sadly, it can't output to an external display.
