Are you saying that other people had been working on and creating what became Apple’s mobile phone touchscreen interface, and they just bought the already near-finished product? If that’s the case I wasn’t aware.
Or if you’re trying to correct me (I assume you’re not, but you never know), I did acknowledge that Apple didn’t invent the touch screen or touch screen phone, the tech has been around since the 1960’s and even on phones since the early 90’s iirc.
