I'm using an Ergodox EZ which I really enjoy and I'm hoping wireless plus a trackball is in the next iteration. Even just being wireless (or a wireless add-on) would be great.
That would be epic. I asked the Ergodox folks about it and they said they’ve experimented with a wireless Ergodox EZ but there’s problems with latency with the two halves being wireless. So I’m skeptical that they’ll produce anything soon.
