Flash could run at 100% native app speeds with no battery hit and Apple still wouldn't support it. Why? It's not part of their overall plan to give Adobe power over the platform.
So no, Apple doesn't need to (and won't) reconsider their position on Flash.
Then people would build Flash apps and just run it in browser and bypass App Store all together. If that happens, not only does Apple give the control to Adobe (and have to rely on Adobe to support iPhone Flash plugin, which is absolutely not what Apple wants), it also loses the benefits of charging 30% of the revenue if the apps would have been sold in App Store.
I know Apple doesn't want to support a flash plugin and was burned by Adobe in the past, but with Android supporting flash now Steve Jobs has less excuses to tell users why they can't view flash on websites. Most users won't understand why they're Android friends can access flash sites, but they can't. Apple could work with Adobe to get a flash plugin on the iPhone, they just don't want to.
Also, people can make flash apps in the browser and that's fine. It wouldn't hurt AppStore sales, cause native apps would be better.
Apple will create more excuses... I'm thinking security issues will be the next focus.
Flash could (and probably would) hurt AppStore sales. It probably wouldn't be significant but some developers would choose to use or keep using Flash rather than creating a native App.
So no, Apple doesn't need to (and won't) reconsider their position on Flash.
