At this point I can only conclude that you don't want to understand. I've already explained that there were a number of manufacturers who had a vision of a smart phone with a similar form factor to the iPhone. Steve Jobs was a fan of Sony, he wanted to run Mac OS on the VAIO line of laptops. As that didn't work out, he ultimately made his own slim aluminium laptop with chiclet keyboard. Richard Howarth who was involved in designing both the iPhone and the MacBook Air had previously worked at Sony. Before Apple adopted the Sony style their products were plastic and/or colorful.

Apple has always copied, just like they copied much of the current iPhone user interface from their competitors.
