The big difference to the keyboard you linked, the Ergodox is an ortholinear keyboard. It is to be expected that that comes with a learning curve if you've only typed on a staggered keyboard. I personally think ortholinear is worth the learning curve.
It's a shame that the Ergodox marketing blurb implies that they invented it.
> archaic design, which we fixed
It was fixed a long time ago, by other people.
Maltron keyboard designs have had this since the 1980s. Lillian Malt criticized "[t]he uneven stretches caused by the diagonal slope of the rows of keys on qwerty" in 1977. PCD Maltron's first demo keyboard from 1976 eliminated that slope.
I use the Freestyle2 Blue, and absolutely love it. Enough that I have one for home and work. I don't have the gaming one yet for my gaming PC, but I'm seriously considering picking it up. The difference is I don't use my gaming PC for typing much, so it's less of an issue.
