In the early 2000s, my firm was trying to work with RIM to develop apps for the Blackberry platform. RIM set the bar very high on accepting partners and our take was that the really didn't want (or felt they needed) external apps developers. This accounts for the paltry set of apps available on the BB in the pre-iPhone days. And those that were available were expensive. They have ambitious plans but I think their corporate arrogance will ultimately lead them to failure. If they haven't arrived already.
I've never been canoeing before, but I imagine there must be just a few simple heuristics you have to remember... Yes, don't fall out, and don't hit rocks.
