I like the look of the NFC keyboard and I'm sure some other good candidates will be found that will meet ppls need. The problem I'm having with btkb + N9 is that once the vkb is swiped off the screen so that the terminal is full screen, you cannot enter what your typing. For me this defeats the purpose of using an external keyboard -having the larger full screen to work with. Indeed, using an external keyboard, with the full screen available, gives you as much visible space to work with as that obtained by a vkb on a device having, roughly, an inch bigger screen. I hope a developer can address this...
