Fair, but the person above you was talking about ThinkPads… Laptops with network adapters that have no Linux drivers are very rare. In the large majority of cases network adapters have drivers in the kernel, and almost all of the rest have drivers that need to be installed after. I used to work at a PC shop where I would very often use a Linux live CD to test hardware if Windows was having issues that seemed to be driver related. 90% of the hardware we worked on were laptops, so I booted Linux on a lot of them. There was never a laptop that didn’t work out of the box on Linux. They certainly exist, but they are not as common as you think they are.
