Although it does show the importance of aesthetics. You can have something, but if its not easy to use or visually pleasing, then its like you never had it.
Easy to use is the main point here, reducing friction for completing a task is an art that not all interface designers do well.
You can see Sony put a lot of thought and love in their console's interface (same with the PS4), putting the user experience in the center, this is no small feat.
If you are not convinced, lookup smartphones from before the iPhone's release, many had all the features, including the touch screen... However with lackluster implementation, it's all moot. Same with the tablets, MS had touch screen support in windows since the early 2000s, it was just bolted on, and nobody cared for it.
