The ThinkBook 14s Yoga convertibles are lighter and slimmer than previous versions due to the new anodized aluminum chassis. They also come with the latest Corning Gorilla Glass protective layer for the 360-degree touchscreen. Processor options go up to an Intel gen 11 i7 Tiger Lake, which can be coupled with up to 40 GB of DDR4-3200 RAM, and there is a Thunderbolt 4 connector, as well.
