also one factor you missed is ROI/Cost... blackberries are practically free
In addition I think the Blackberry price point for long term life cycle is much more attractive than the Iphone's...
For Blackberry devices, we're getting them practically free (we pay $10 or something for a 3G Curve w/ no contract--actually there was a time a few years ago when they PAID us to get newer model blackberries). Iphones we don't have a contract per say but they have a 2 year policy that you can't order the same person an iphone within that 2 year policy..
Now, let's examine what happens in real life... It's not necessarily the up front price that matters, but the life cycle of how business users consume the phone. What happens in a year? I'm the type of user who considers the Blackberry to be built like a toy. It's cheap and I don't necessarily care that it only lasts a year at best, because if it breaks it's $10.
I recently switched to an Iphone, which finally is at a price point of $50 which puts it in the realm of possibility to get for business users without having substantial justification over a BB. The problem though is what happens a year from now when the iphone accidentally breaks? (...it already did actually. a small amount of condensation from a cold glass sitting next to my device caused the 3gs to completely freak out and is now dead). Or what happens when a user leaves it in a cab (happens several times a year)? Because of the 2 year period on the Iphone I'm somewhat screwed, ehh? My option, I believe, is to now pay $500ish full price for a new device. Most businesses will not be too happy about that. With a Blackberry at $10 and no contract, I order a replacement and it's no big deal.
(I doubt there are any companies out there getting a better break from AT&T on the iphone than that too. So while my #s may not apply to everyone, I can at least reasonably assume that it's probably not a cheaper device for others either)
