I have mixed feelings about the iPhone. On one hand, the device itself was very sleek for the time and its touch-driven, easy-to-use interface was a revelation for 2007. On the other hand, it was the harbinger of the locked-down, walled-garden hellscape that is the modern tech industry, and its success paved the way for horrors like Windows 8/10/11 and the modern Mac OS which gets very testy if you try running app that hasn’t been notarised by Apple.
