30% sounds like a lot, but that looked like about 300-400 milliseconds, which isn't very interesting.

(That said, showing that you could port a native iOS app to RIM in X days would be an interesting metric, since the size of the App Store dwarfs the BB Store.)

(RIM, are you listening? No one cares about sub-second speed increases, Flash, external SD slots, multiprocessor whiz-bang GPUs, and most of the rest of your marketing material. Make a product that amazes my parents, and you've got something. Sell to the techies, and you seal your fate.)
