Actually BB is why I added the "(or pager)" to my comment.
BB was a two way pager (and later email) that they literally crammed audio in to (the first phone version REQUIRED a headset as it didn't have a speaker/mic).
They made the mistake everyone did. They made an X and so they tried to cram new things Y and Z into it because they were an X company. And it limited their vision of what they could do.
Jobs was only looking for 10% of the global mobile phone market in the 2007 keynote announcing the iPhone. The iPhone was so well received it demolished Nokia and RIM's dominance in the space of a few years.
