Lenovo IdeaPad Gaming Chromebook 16 review: Stream games while doing homework

On paper, a 16-inch Chromebook with a 1600p full sRGB 120 Hz display sounds overkill. After spending just a few minutes with one, however, we can't look back. The Lenovo lives up to its name for being both a cloud gamer and a productive Chromebook.

Lenovo IdeaPad Flex 5 convertible review: Powerful entry of the small i3-1215U

With simple equipment but a few highlights such as Thunderbolt, a keyboard illumination, and of course a touchscreen, the IdeaPad Flex combines an office laptop with a 14-inch tablet. The fairly affordable i3 of the 12th generation impresses with its silence but is also surprisingly fast.
