I used to work in their cell phone sector, then moved to corporate IT. The joke at the time was: A meeting was called between Chris Galvin (the CEO at the time), and the heads of the various departments, to show their new technologies. The cell phone guy says "We have a new cell phone, that you can also send and receive pages on it". The guy from the 2-way radio sector says "We have a new radio, you can use it to make cell phone calls on too. And we are working on adding paging capabilities to it". Then the guy from the pager sector plops his device on the table, and says "Our new pager is 2-way, and we've add the ability to make calls on it, with a earpiece attachment. And it has a built-in FM radio".

And all the devices took a different power adapter, and different battery.
