For example, Microsoft, Lexmark, and several other makers of keyboards were trying to gain better share of the market pie by designing ergonomic keyboards.
However, some designs results to odd shapes such as irregular slopes and curves. These oddities are quite expensive. The beauty of natural keyboards is that it provides more convenience. You need not reach out to tap the keys. The new designs may have the look but may not have the feel. What I mean is that a user may love the design but may not like to use it. In other words, as a designer, you need to redefine and remember what a keyboard is and does. In every technical design you make, you should always redefine its function so as to fulfill and improve wrist comfort.important source
