The iPhone/iPad space is more about media consumption than development, nevertheless there is a HUGE demand for developers (and a huge pool of aspirants), most of whom already own Mac OS X computers and possess some of the skills (Object-oriented programming, scripting, etc.). The iPad is dominating the tablet market 10:1 and is in great demand for enterprise appliance development. You are no doubt right about Android becoming another pervasive mobile/tablet platform, but I seriously question your prediction of 10:1 dominance. iOS will remain a major force until the next tectonic shift (wearable?, implantable? digestible? devices?). I have some visibility into the Apple world via a family member who is a major iOS developer and training shop. His business is phenomenal, and the target market is far broader than conspicuous consumers.
