Personally, I think more than 50% of users would benefit for more flexibility than iOS offers, even at the cost of less ease of use. I don't think it has to cost that much ease of use though. I think the ideal for most people is somewhere in between Android and iOS, but probably closer to Android. Android is not that hard to use. It is also not impossible to have a highly curated app store like Apple's, and allow apps from other sources at the same time of people want to install them. Ideally we'd have more diversity in OS implementations I think, based on one or a small number of actual OSs. Android based OSs that are more heavily modified to be easier to use etc. This would be easier I think if phones were more like PCs in that you could install your own OS and get the drivers for your hardware. I think Android is somewhat moving in that direction so there is hope for that in future.
