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 Acer Chromebook Spin 311 made our Top 5 Light Use Laptops, at #2 and #3 (best budget). 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 Chromebook Spin 311 is the cheapest convertible worth considering for kids, casual users, and couch browsing, but the small HD display is its obvious ceiling.
We score light use laptops on Value (35%), Ease of Use (25%), Battery Life (20%), Reliability (15%) and Display (5%). On that basis the Lenovo Chromebook Duet Gen 9 totals 8.6 out of 10 and the Acer Chromebook Spin 311 8.5. The widest gap is Value, where the Acer Chromebook Spin 311 scores 9.6 against 9 for the Lenovo Chromebook Duet Gen 9: price for what you get. Reliability also separates them: 8 for the Lenovo Chromebook Duet Gen 9 versus 6.8 for the Acer Chromebook Spin 311. The Acer Chromebook Spin 311 claws back ground on Battery Life.
