iOs 6 is a joke from what I've seen it's nothing like the jump from 4.0 to 5.0 was. It's more like 5.3 or 5.5 at the most and almost all of the "new" features are already running on Android for years. I love my 4s, but iOs without a jailbreak can't compete with Android at the moment. What the iPhone does it does extremly well but it lacks a lot of standard features.
I also hate that Apple thinks we're excited about features like opening Apps with Siri or sending a text when declining a phone call. That's basic stuff which should have already been there a long time.
Dunno, ios6 seems like a pretty significant update to me. Redone maps app from the ground up (my most used app), expanded Siri which also works internationally (huge for me, as I'm in Canada), FB integration, shared photo streams, passbook (which looks ultra useful), Facetime over data which many have been asking for, expanded phone options, better safari, a bunch more accessibility features, remodeled stores, and probably a bunch of small tweaks/features that havent been announced yet, not to mention software features exclusive to the next iPhone which obviously we don't know about yet. How many real features did ICS/Jellybean add compared to these? Every single time a new version of iOS comes out, so do the trolls proclaiming how everything 'has been in Android for years'. Even if thats true (which it isn't) who cares? Its the implementation that counts, and you should assess a product by its own merits and how it compares to the previous version, not by random product X which has its own pros/cons. Just like the copy/paste delay, it was irrelevant. Yes Apple was late to the party, but they also had the best implementation. Apple is methodical when it adds features, preferring to implement, package, and market them correctly rather than just fulfilling an avalanche of bullet points.
I own both a 4S (unjailbroken) and a galaxy nexus, and your line that it can't compete with Android is complete BS. I can honestly say I miss nothing major from the GN when using my iPhone. They have different strengths, but iOS still has a clear advantage in several areas including performance, stability, useability, consistency, and most important of all app ecosystem, both in quality and quantity. Maybe for geeks that like to tinker with everything it 'can't compete' for for the vast majority of consumers, it competes just fine in the important areas. Most of the people I know who have an iPhone don't even know about or use some fundamental features. Try to look at the big picture, not just your own personal needs/wants. Most of the people I deal with are not technically inclined, which is why I find those proclaiming Android as 'far superior' hilarious. Most don't care about ultra customizability. They want familiarity, reliability, consistency, etc. It's why I purchased a 4S for dad, brother, and sister because I know for a fact they'll be happiest down the line with it, and I'll have less issues and support to deal with.
