Sure they're are taking a beating right now. They were a powerhouse in the early smart-phone wars, and they don't seem to know what they are doing, which direction is up, and lack a clear vision.
But I believe they have a huge ace up their sleeve that is being somewhat ignored. QNX. Not as the operating system for their devices, though obviously that is important too, but as a popular embedded operating system 'in everything from in-dash radios and infotainment systems to the latest casino gaming terminals' (from the qnx.com website).
Blackberry has a history of making some pretty good hardware, and they have systems embedded in enterprise (BIS) and consumer devices (QNX). Those who are only seeing the currently mediocre products I think are selling RIM short.
I don't own a Blackberry but apparently I interact with RIM products everyday.
