It's not any more criminal than the failure of Eastman Kodak.
RIM decided to avoid the fun smartphone market for almost 6 years. Blackberry was the business phone, for people who couldn't use cameras, who wanted a physical qwerty, who didn't need videos or games or streaming music.
Thing is, the price difference between buying a Blackberry, and buying the same trendy phone as your friends, and just not using all the non-Blackberry features of that trendy phone, weren't really that much. So sales sagged.
THEN, they got hacked and nobody got to use their Blackberries for 5 days straight. I think that happened twice.
So that loses everybody who had a Blackberry and didn't need to pay for daily email. Then there's everybody who had a Blackberry and prefers a phone that's never been hacked, and Apple is willing to lie about not needing security. Then federal courts that had banned cellphone cameras, just freaking gave up and allow them, so,why bother not getting a Droid?
The core joke of Hitchhiker's Guide to the Galaxy is that of course no civilization would develop personal computers with instant remote database recovery, and then waste this technology to find good drinks.
Steve Jobs has ruined this joke.
