Why would I increase signal congestion the room with a device that is almost never moved? Why would I switch a device that has potentially decades of lifetime to a device that has a soldered battery and thus could die within years because of it (big quality keyboards rarely come with standard tubular batteries). Which on top of that has worse latency and more potential (connection) issues?
