Depends on the use case it’s being purchased for. All laptops and most motherboards come with usable wifi for ordinary use, so it’ll be a special case, like greater power or driver support for monitor mode.
But if we’re talking a consumer oriented purchase, then a working driver included in the OS is high on my list. More than once have I had to help people get a wifi driver downloaded to a phone and then transfered the driver with USB. Which itself can be a handful as most third party cables are only for charging. I reckon that it wouldn’t cost a lot to put 64MB flash memory on a wifi dongle, but I have yet to see it… Anyway that’s a bit of a rant, but you definitely want a way to get the driver.
Other than that? What everyone else has said about standards, speeds, and whatnot.
