The models may still be cool.
Just because some of us have concerns about ergonomics doesn't mean *everybody* does. In fact, looking at the ergonomics of a lot of the products on the market one might think the majority of consumers don't value ergonomics very much. For a lot of products (and I'm not just talking readers) the bulk of the learning curve is in how to hold the darn things without killing yourself.
Or the signal.
