Choices and Simplicity do not go far together
I think that is why I cannot switch away from my mac or iPhone. Apple is incredibly simple to use because there are not too many confusing choices!

At ParentSquare, we try and solve it with 'repetitive design': Making new features fairly similar in design and usage to the already existing ones keeps the learning curve low.
