I think people who want RIM to keep up with Apple and Android are missing the point.
iOS and Android are consumer driven operating systems born out of the consumer market. There sole focus is the consumer experience and if you happen to be able to be productive in business with it it's a plus.
RIM was born out of the corporate market, it is first a corporate device, with consumer enhancements added to it. I think RIM is in a different lane altogether and should not be expected to compete with apple or android.
I enjoy my Blackberry. I would like for certain things to be improved, primarily the browser, but outside of that I don't need HD video capture and editing, or many of the other features touted by the iphone and android users. If I did, I would get one of those devices.
I believe it is an apples to oranges argument. Just my opinion.
