Most wireless cards out there work just fine. When I had to use a laptop with a Broadcom chip for uni I used my Android phone as tethering (charging it as a bonus) and the guy sitting next to me just used a dongle smaller than his thumb.
Most people (even developers) aren't willing to open up their laptop to replace their laptop wifi cards or to have to use dongles to get on their wireless or to play endless hardware roulette.
