I never would argue the fact that an iPhone is a "toy." It really is the most fun little toy I've ever had. However, I think it also has the capabilities to make it so much more. A crackberry has the same (and actually a little bit more) to offer business-wise, but cannot compare to the iPhone for overall "fun" factor. As both platforms continue to develop I think they will move towards eachother as the iPhone catches up on business capabilities, and RIM catches up on overall fun factor.
Just because the BB App World is late to the party doesn't mean that it won't be successful. Sure it may not have the same volume as the Apple store and may not catch up anytime soon (or even), but it doesn't have to beat the Apple store to be a success. As long as it serves it's purpose well for BB owners, that will determine it's success.
IMHO, of course.
