I get not loving the "Apple invented everything" mantra some people have, but the iPhone genuinely redefined the smart phone category. The industry has 100% coalesced on the model invented by Apple. Nothing like this existed as a full package before the iPhone and now are almost universal:
- No physical keyboard + touch keyboard
- Modern OS kernel (not embedded specific kernel)
- Desktop browser engine
- Capacitive touchscreen + finger instead of stylus - one or two phones had capTouch before, but they were far from standard, and they still had physical keyboards for typing
- Vertical by default orientation
- Short 1 day battery life in favour of more power/features (weird to list, but was a bold move everyone mocked then followed)
They totally took out the existing market (Blackberry, Windows Mobile, Symbian, a variety of OEM OSs). Android succeeded but came after, still had keyboards on its flagships the years after iPhone came out (G1, Droid), and took these design cues from iPhone.
The Mac GUI with mouse+keyboard+windows was also huge. Admittedly not first to invent it (Xerox PARC), but first to ship it as a package is still hugely impressive. Few people commercialize a new product before it existed in some lab.
