Our Verdict
Lenovo Chromebook C340 15 (2020)
Lenovo IdeaPad Slim 3i Chromebook 14 (2023)
The Lenovo IdeaPad Slim 3i Chromebook 14 (2023) and the Lenovo Chromebook C340 15 (2020) are both good budget Chromebooks. The C340 has a larger 15.6-inch screen and a full-size keyboard with a Numpad, and unlike the Slim 3i, it's a 2-in-1 convertible, so you can use it as a tablet. It also has a sturdier build and a better keyboard and touchpad. On the other hand, the Slim 3i has a brighter display, a better 1080p webcam, and a slightly longer battery life.
