How they differ in real use
Built from our light use laptops scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Lenovo Chromebook Duet Gen 9 and the ASUS Chromebook CM14 made our Top 5 Light Use Laptops, at #2 and #5. The Duet Gen 9 is the most flexible light-use pick and the only detachable here: it pairs a 10.95-inch 1920x1200 touchscreen with an included keyboard and kickstand cover, and its efficient Kompanio 838 runs roughly 10-12 hours per charge, though its short-travel folio keyboard is less comfortable than the clamshell Chromebooks for long typing sessions. The ASUS Chromebook CM14 is a sturdy basic Chromebook with a usable keyboard and display, but it is less compelling unless its exact configuration is discounted.
