I worked at RIM/BlackBerry in 2005-06. It was my first engineering job. I was in my early 20’s and at some point, way before iPhone, I went to my manager and suggested we should add a camera and some multimedia features to the device, because that’s what the younger people wanted and used. He said - but why, BlackBerry is all about serving the business people market. We argued. Turns out we were both right and wrong…
I used to watch his YouTube videos all the time. And he used to talk about his days in RIM as he was one of the first engineer there. You reminded me to check his channel again and looks like he did a reaction video to the trailer.
The 8100 was released in 2006 with its camera. I am sure it was in development for quite a while prior. That phones would all have cameras was a foregone conclusion by 2005.
Although only getting camera support in 2006 was rather late, and I wish I could find a good contemporary source for the Mike Lazaridis quote circa 2003 that "Cameraphones will be rejected by corporate users." (and thus Blackberrys won't have cameras, as their customers are companies, not end uses) from a couple of years earlier[1].
