This is a gimmick to me and to anyone else that has a ethernet switch on their desk. The fact that it is only an antenna means it is only useful for desktop users, no use for laptops. Would be better for them to have an integrated M.2 A+E slot for wifi cards and the antenna could then either self attach or be attached to desktop. This M.2 could be connected most ideally by USB-c output(The same USB C that should be PD capable) or USB3. As it stands it can only serve a sliver of the market(Those with Wifi with externally exposed antenna ports). Very gimmicky...
But for me, its hardwired only, can't beat the latency or stability. I have plenty of USB 2/100MBPs & USB3&c 1Gbit adapters lying around for those machines missing ethernet. Wifi is what you use when you need to be mobile, not at a desk.
