EDT In a statement to Mashable, Microsoft confirmed that it will no longer sell the $999.99 configurations of its flagship Surface Laptop 7 and Surface Pro 11 with 10-core Snapdragon X Plus processors,

Both new Surface devices carry the “Copilot+ PC” designation Microsoft gives to high-end computers with a so-called neural processing unit. It handles things like real-time translation in video calls or image generation, freeing up the CPU — in this case, Qualcomm Inc.’s Snapdragon X Plus — for other tasks.

A drop chamber is designed to validate Microsoft’s simulation data against the reality of dropping a device on concrete flooring. The drop chamber was key to developing Microsoft’s removable battery packs on its latest Surface devices, for example, to ensure any drops wouldn’t puncture the batteries.
