My first three phones were Nokias and I loved them. That was in the days when battery life was the phone "feature" we cared most about.
However, the switch to an iPhone was a no-brainer.
Can you imagine what the Nokia R&D team felt like when they first saw the iPhone? Their market had just witnessed one of the biggest disruptions of the digital era.
The cell/mobile phone market changed overnight - perhaps "evolved" would be more appropriate.
