Lenovo prices the ThinkBook 15 at around US$870 for the new entry-level Intel Comet Lake variant. The Core i5-10210U-powered device also comes with 16 GB of RAM and a 512 GB SSD, along with a 15.6-inch 1080p display. While that all sounds promising in theory, the device cannot get the most from its quad-core CPU.
