When one decides to no longer use desktops and completely moves everything to the mobile space, especially with security in mind, what are some recommended setups for using a keyboard and mouse at the same time? There are some claims that bluetooth is inherently unsecure. Turning on the usb port leaves a great attack surface, and since all mobile devices have only one usb port, there is no way to use a cable keyboard and mouse at the same time. Any ideas?

    Plugging in a USB device you own while the phone is unlocked is arguably a reasonable risk (and not clearly more risky than activating the Bluetooth stack).

      in_search_of_privacy I've replaced my laptop with a portable monitor and a wireless keyboard + mouse. It was a bit odd carrying around a "disassembled laptop" for a while, but I've found it quite a comfortable setup for Android's desktop mode. I've also never much liked laptop keyboards or trackpads. I would definitely reccomend this setup, as it was the only way I could move away from insecure desktop OSes. Cables really are a hassle and only needing one makes this much easier to handle (compared to three cables and a dongle).
