Yes the impact of the battery would be unsolvable. Even if it isn't very bad, just a bit bad, the issue is that you have all that extra layer, consuming battery life. And battery life is probably the biggest issue in portable devices these days. There is no way to put a bigger one to solve the problem. There is no bigger one, and there won't be one in the next years probably. Yes, the flash to native ban suck but it's probably not the way the flash works on the iphone with cs5 given the performance I've seen. As a programmer, it has no sense to vorbid a language, as every language are sort of equivalent in the end. I would like to see flash works on iphone, and androids but the current port is slow for even the simplest thing. Even a single movie clip was slow on what I've seen. It's not possible to write a responsive flash app if even that is slow. There is no code, it can't be poorly written...
