True, but I see them as very different products. The BB is tailored to the executive or mobile manager types who want instant, no frills synchronization with their Microsoft Outlook or equivalent. The full (push button) qwerty keyboard that many of it's models have is also demanded by many of these folks.
The iPhone does emails but full synchronizing with Exchange Server proved difficult at first (I'm assuming it's no problem now)and the touch screen keyboard was seen as an inconvenience by the BB type folks.
Both are great products but I think it's a good example of how they are catering to two very different personality types and business needs.
I'm Riffing. People usually stop me when I'm riffing. Or carry on without me. That's also an option.
