You are both saying the same thing, I guess. grandparent states that it is "possible to do flat design well" and gives examples (Apple). I don't have anyhting Apple, don't like it, but I do find their designs awe-inspiring. To me, this comes from their investment in detail. The issues you describe "Does making "New List" a flat button and thus barely distinguishable" is real and an example of bad design. Not a proof that all flat-design always is bad. It shows that too little time and effort was poored into this piece. I'm not sure how I would fix this particular issue. But I'm confident that within the contstraints of "flat design" and time and effort (investment) in details, this is solvable. I'm also confident that without the constraints of flat-design, the time and effort needed would be far less. But here we are.
