I don't know why so many people feel iOS is outdated. I'd get really frustrated if Apple started changing its interface every few years just for the heck of it. iOS works well for me and does what I need it to do. It's intuitive and smooth. I'm sure it will gradually evolve; it's only five years old, after all. If a system works, why muck it up? I don't see much ground-shaking interface evolution from Android. The only OS to get a major makeover recently is Windows, and we'll have to wait and see how that one turns out.
