until the next groundbreaking innovation you didn't think of.....
That's a possibility but my point is that innovation in the smart phone space is rarer than we think.
Take laptops for example.
Laptops were extremely bulky, heavy, terrible screens, and poor battery life.
How many innovations have been created over the past few decades in that space?
They got to a point of being very comfortable, light, powerful, and amazing devices.
You have a few "recent" innovations like the Macbook Air and chromebook, but otherwise, hasn't most of the technology stayed pretty much the same while getting incrementally better? That's just the way technology develops.
