Actually, I'd contend that except for app selection, Windows Phone 8 is superior to iOS in many areas. I switched from iPhone to Windows phone, and I'll tell you without any reservations, I couldn't go back--iOS is simply too primitive from a user experience and capability point of view.
While iOS is a perfectly good OS, it's not very good at getting your data front-and-center. WP8, on the other hand, excels at this, whether that means the basics like calendars and contacts, or whether it means deeply integrated social media or the ability to put "deep links" from apps on your start screen to fine tune the data you have rapid access to. I'll give you a few examples of why I say this.
In iOS, say I've got Pandora and a list of maybe 30 stations. I can launch Pandora and, if the custom station I'm looking for is on the front page, I can launch it, so two clicks. If not, I have to browse deeper into the app, find what I want and launch it, so 3-4 clicks.
In Windows Phone, I can pin every individual station I want straight to my start screen and have literally one click access to the station.
In IOS, if I'm using Evernote or OneNote to keep my notes, there are many things I can do. I can make new ones, access old ones, etc, fairly easy. If I need to get to a specific note in a specific notebook, I launch Evernote or Onenote, navigate to where my notebook is, and scroll to find my notes. At least 3 clicks, depending how deep I need to go.
In Windows phone, I can directly pin notebooks or even specific notes right to my start screen for not only single click access, but notification if one of my shared notes has been modified by one of my coworkers. I can't do that in iOS *at all*.
In iOS I can navigate into my contacts app and see the people I have saved. Pretty slick. If I want to see what their social network status is, I launch the appropriate app. If I want to see my history of contact with that person, I have to go to my a)call log, b) text log, and c)social app (say, facebook or twitter).
In Windows Phone, I go into my People app (contacts plus so much more), and in one location I can find my contact and see all the ways to contact them, I can see their latest social networks updates, post to their facebook wall, reply to them on Twitter, LinkedIn, Facebook, text messaging, Skype, Instant Messenger or facebook messenger in a clean, single, unified interface. I can see a single log with all of my contact with that person: when I last called her, my most recent text messages and emails, including dates, any upcoming calendared appointments, etc. It's a VERY powerful application, and nothing on iOS matches its versatility.
If I want to keep track of a few "favorite people" without delving into my contacts, I can't do that easily on iOS. With Windows Phone, I simply pin those people to my start screen and their tiles will automatically update when they message me, add new pictures or posts to their social networks, call me, or whatever else. If I only want one tile and not a bunch, I can add my favorite people to a group and pin that, and it'll update with an aggregate of all their information as the updates come in. If I want all of those people to communicate in a unified way, I can add them all to a "Room" and pin that room to my start screen, which allows every member to message all the rest, share pictures, documents and conversations in a private space. I can't do that on iOS at all.
Now, there are some things iOS does that WP does not do, but they tend to be app-centric things. For example, there's no compatible Square, Intuit or PayPal credit card swiper on Windows Phone (as far as I know, last time I looked was a couple of months ago), but that's something that can be fixed with apps.
It's fun, I know, to badmouth "competing" OS's and claim they're inferior and all that, but it simply isn't an accurate or honest statement to claim that "iOS is superior to WP8" in any kind of unilateral sense. Yes, it has some things it does that WP8 doesn't, but WP8 equally has many useful, well implemented features that iOS simply does not--and in its present form, cannot--offer.
. 64 bit is a good direction to go in, but it will never matter to the iphone 5S. 4K will never matter to it, either--why would it when they haven't even gone to HD screens yet *at all*? The iPhone 5S doesn't even do 720p, which is the baseline for HD, much less 1080p, to say nothing of 4K
