Sad thing is, at least 3/4 of the users there would be better served having an iPhone or an Android phone. They badly want their Blackberry to be one, and it's not going to happen.
The phones are different. Everything about them. If you're tied into the BB corporate infrastructure, you're much better off with a Blackberry. If you aren't, why limit yourself to devices that were built ONLY to be compatible with the corporate infrastructure you're not using? Blackberry's day in the sun is about to be over. Maybe it will be Android to overtake it, maybe not, but the fact that RIM is moving away from their tried and true business model speaks volumes about their faith in their current market position.
I'm tempted to try to retrofit a blackberry Storm shell to run on the internals and LCD of a Hero and sell it on the CB marketplace. 4 buttons and a touchscreen...hmmm. Would be a fun project and something tells me I could sell as many of them as i could make lol.
