Re: "And bluetooth with Win10 is an iffy affair"
i have various bluetooth devices for the Macs. Provided the batteries have sufficient juice they are hassle free. I have an Apple wireless trackpad for the old iMac and it's fantastic. Puts itself to sleep so you never need to switch it off.
I have a Satech wireless keypad for this laptop and it too is absolutely fine. I can connect my Moto phone to it with bluetooth but the Moto software can't handle bluetooth file transfers, just wired.
