The Precision 3560 is new for 2021, and with Intel's Tiger Lake-U platform. The 15-inch mobile workstation features a new design from last year's model with a larger trackpad and a new keyboard. However, the dedicated mouse buttons have gone, and the pointing stick appears to have been omitted too.

Shame that the very few options we had for models with touchpad buttons and pointing stick - hardly 1 or 2 are also all killed by Dell.
