First, you can make something clear. The interface is not something that is something. The papers are not ergonomic and non-ergonomic, ergonomics ergonomics are good or bad. Therefore, if the advertising says, the new panacea, it is ergonomically correct. Not only should the interface is good or bad.
Therefore, good ergonomics worth the time and / or costs associated with them and development? Of course! Good ergonomics is the gift that keeps. But I have an ergonomic design, perhaps, so I'm biased.
