I'm going to disagree with that. iOS, at least until June (and we don't know what happens then) is really close to 20-26 months behind Android. When iOS was compared to Froyo, and even somewhat in Gingerbread, there was a debate about which was better in terms of total functionality (not just the one perspective of easy for your grandmother to pick up and just use). Since Ice Cream Sandwich pulled ahead of iOS they haven't had an answer, and both builds of Jelly Bean are vastly superior to Ice Cream Sandwich. As of today, Android is, as a software system, way ahead. That being said, there are a lot of examples of poor execution with customized versions of Android that take it down a peg or 10 pegs from it's potential. This is why I keep saying that I hope iOS brings the heat this year... because right now Android is competing only against it's own imagination, not against the market. There are no other serious contenders right now in terms of software innovation. I hope you bear in mind the distinction between, selling well, being a great device, and being a more advanced software package.
There are millions and millions of people with iPhones and they love them and 90% of them have the right device. There are around 3 times as many people with Android phones and they love them and 70% of them are right. I'd guess 95% of mainstream consumers would be happy with either or, switching between, etc. as long as they never knew the other existed, because mainstream consumers are looking for basic functionality plus some nifty tricks the device can do. Power users, such as those that develop software, or are heavily invested in the thought processes attached to that industry, ought to look at the larger picture of meaning within their art.
(Percentages used in the 2nd paragraph are intended to convey context and may not be statistically accurate... there is no survey that i know of that actually measures that. They're more my estimation from reading and talking to people about devices, software and the philosophies, if any, attached to that conversation).
