That argument could be applied to most instruments... the violin is hardly a friendly instrument for a beginner! So should we put frets on it? Oh, sorry, I've reinvented the Viol!

The charm of an instrument is often rooted in its idiosyncrasies, otherwise why would people persevere with a melodeon when a piano accordion is far simpler?

Once you change its basic design it becomes something else... which is how the Duet was born.
