The Intel monoculture in laptops has been a boon for linux compatibility. A random mid-range laptop with the an Intel CPU, Intel WiFi chipset, and integrated graphics will usually run linux straight out of the box. Most webcams in laptops are UVC devices so also work.

Desktops are somewhat more hit-and-miss, as are discrete GPUs (I hear the newer AMD GPU drivers are much improved, but have no personal experience with them).
