I’ve been using mobile phones since the mid-nineties and have seen several companies impact the industry. Motorola and Nokia helped shape much of the earlier years of mobile phones with the latter introducing me to my first “smart” phone with the Communicator. 

Then came BlackBerry that pushed productivity on mobile phones with push email and instant messaging and I was using one all the way till the iPhone grew up. What BlackBerry did for productivity, the iPhone did for touchscreens and that has helped shape the last decade of mobile phones.
