Would've been great if it supported wired mode. Until then, Filco Convertible 2!!! Looks like it's the only one around that supports switching between wired AND Bluetooth.
qwertyyyyI've had a Filco Convertible 2 with Cherry MX Blues for the better part of a year now (typing on it now), and I have to say, it's rock solid. I had been looking for something for its exact specs for years, and when it was finally invented it did not disappoint.
Takes virtually any MX keycaps you want to throw on it. Full-sized mechanicals aren't in style right now, but I use the tenkey like it's going *out* of style — it works great. You can hot-swap between four devices and a wired connection (which works great for me because I include my phone and iPad in my work and home battlestations), and the battery only needs recharged about twice a year. Twice. A. Year. This thing is amazing.
