The problem with this line of reasoning is you are using a specific outcome to criticize an entire process: Apple failed to produce an iteratively superior product, therefore their process is "fiddle and fuddle." Their process of innovation and iterative improvement brought us the Macbook Air and so many other great products. It seems very short-sighted to claim a particular model is the pinnacle of design and user-experience and they should quit now. Will they always succeed? Certainly not. Should they keep trying? Definitely.
