I think it looks great: take the basic idea of the Kinesis Freestyle, and then just execute much better [more thoughtful layout, much more solid build quality, much nicer switches and keycaps, etc.]. It’s not my dream keyboard, but I think it’ll be a winner, and wouldn’t hesitate to recommend it to anyone used to standard ANSI keyboards asking about something more ergonomic or pleasant to type on. Looks like the learning curve is basically zero.
That said, Matias, if you’re setting up some possible switchable settings [like ctrl/caps swap, etc.] I definitely recommend looking into the ability to make one of the spacebars work as backwards delete. Getting the delete key directly under the hands is one of the biggest and easiest ergonomic improvements to make, and doesn’t require much practice to learn.
Alternately, using one of the thumb keys for shift, and using the shift keys for something else, such as delete or Fn, is also quite nice. [But probably takes more time to learn]
