Where we could, we certainly tried to avoid it. The bigger problem is just the opportunity cost with regards to resources involved with the transition.
Another thing I'd be curious about is the line at which the opportunity cost of not making the transition surpasses the cost of not developing new Flash features.
When a bank CEO, who has no idea about anything except "Well Adobe is a big company and I've never heard anything about this W3C, and how long will it take? How much will I make off it right now?" hears (if he even does) that Apple doesn't like flash, he won't care.
