I'm not sure what they use the WiFi for. It would make more sense to use Bluetooth if they wanted to offer wireless connectivity to the laptop. In any event, mine does not have WiFi and uses the supplied USB cable to connect to my laptop. If they are using the WiFi version for connectivity to the laptop, then it's probably better to go with the non-WiFi version if using the supplied software, since it won't work properly unless network access is disabled on the laptop.
