The thing is that yes, these were all pretty big porting projects, but they were also things that Adobe would have known about years in advance, and just never bothered to deal with until after it was an issue for most people. When they knew about an upcoming platform change a year or two in advance, and didn't bother to deal with it until a year or two after, I have to assume that they just never cared. That's why Apple doesn't want to deal with Flash - they don't want to rely on a company that doesn't care about Apple or its users, and they don't want to be beholden to Adobe's schedule of 'we'll support that next year when users are hurting for it'. When Apple announced location support in iPhoneOS 2.0, for example, including GPS for the iPhone 3G, would Adobe have had it ready for launch day? From their history, Flash would have waited until the next 'major release'. Flash-based apps would have had a reduced feature set, and the App Store would have been full of applications that couldn't support the latest and greatest features, distracting from applications that properly supported 2.0 from the start.
