I’m surprised that RIM has made this far. At first a total refusal, and then a total failure to compete against Apple and Android. RIM execs blew more calls than a monkey flipping coins could have.
I have a different take - it's not as much about Apple as it is about RIM failing to keep their quality standards up to the level needed by their existing customers.
RIM's success was built on the reputation that its hardware and software was rock solid and secure. Their enterprise infrastructure and connectivity was the best available, their device / software bundles offered exceptional functionality, usability, and reliability, and their customer service was very good. Speaking as a long term customer - not anymore.
The network has had major, multiday outages, the software reliability has taken a nose dive, and their browser is garbage.
