Capacitive touchscreens are a big deal but it kind of minimizes the work of the other technology that goes into a smartphone, like wireless internet, low power mobile CPUs capable of 3D graphics, lithium-ion battery packs, etc., to say nothing of the design engineers that worked on the exterior, the hardware, and the operating system. Crediting the holder of a patent from over 40 years before the iPhone hit the market with the creation of the iPhone is stretching the truth at best.
