We use the same panel dimensions and resolutions as the 13.5" Surface Laptop and the same Tiger Lake CPUs. Beyond that though, we have 1.5mm key travel vs 1.3mm on the Surface Laptop, four configurable ports supporting USB 4 instead of one each of USB-C and USB-A, FHD webcam instead of HD, memory upgradeable to 64GB, storage upgradeable to 4TB, and a design that is open for end customer repairs (rather than "authorized service centers").
