No it isn't. By definition, no Android product is an outstanding consumer device since Android itself is particularly viscous malware given how badly Google and their carrier partners abuse it to snoop on their customers. Advertising supported system software is an extremely evil concept. This or that Android device may have impressive technical performance from time to time, but that does not make Android a good consumer choice.
The App Store review team (well, at least some of the members) isn't as thorough as you might think.

Indeed. The download should just work. It seems trivial to detect which version should automatically get selected.
And I agree that doulbleing the download size is a foolish way to avoid the need for the customer to have to choose the version himself. Some sort of auto-detect seems like the way to go.
Your link does not make your point. It looks like the Atom chips you cite are for tablets and Chromebooks, not phones. So far, Atom continues to be a no-show in the phone market since it can't compete with the lower power usage of ARM. Your link does not appear to invalidate Apple's claim of first 64bit chip in a smartphone.
Nor did you prove your point about A7 not having desktop performance. I'm not sure there is a definition of 'desktop performance' in the first place and in the second, I've yet to see any specs on the A7's performance other than the Apple presentation bullet points. I think we'll have to wait for some data to argue their statements.
Yes, this would be fantastic. Also, this should be used to detect non retina devices and retina to give the smallest sized app download; this should've shipped with iOS 4 in my opinion!

Oh, please no. I don't want my lethartig java apps to become bigger bigger and even slower to start or switch 😛 in between Closing the browser and starting the camera app I could sometimes eat a double whopper meal, shave, shower and take a nap. Damn, my Note needs probably more RAM and 16 cpu cores 🙄

Seems weird indeed. Hardly unexpected that note was pulled. It will no doubt reappear in the coming weeks.

Transcoding audio with iTunes 11.1 Beta 2 uses over 400% CPU. :/ Unfortunately, I can't remember if that's new to iTunes 11.1, or if we had that on earlier versions.
Mavericks version is bringing better GPU acceleration (or acceleration for the first time, embarrassingly?), so that will be an improvement, too. Not to mention the new accelerated scrolling, which will make things SEEM faster.

I don't see a lot of value in creating separate 64-bit & 32-bit versions, or even a 64-bit only vs Universal version. The lions share of the download size for an App is not code, it's media - which are quite happily shared between both architectures. So a slightly larger download size is much better than creating consumer confusion with multiple versions.
Having said that, I can see it being feasible for the AppStore to host multiple builds and deliver just the build that is relevant for the user's current device. Since Apps are not (often at least...) shared from device to device (who really uses iTunes to manage their iOS apps anymore 😕) this would be completely transparent to the user, with the benefit of faster download times, less storage required, and better (potentially at least) performance when it's available. This would also be cool for Retina/non-Retina versions - maybe the Asset Catalog feature in Xcode 5 will make this feasible, or maybe we'll see an end to non-Retina devices before that, who knows 🙂
sounds like your JVM wasn't properly optimized for the architecture... Such is life when you're compiling to bytecode and not native code. 🙄

Double binaries are only coming later though, so in the meantime, we should expect 64-bit only apps. And I doubt the single binaries will be pulled once they are compiled together.
In simplest terms, the number of bits refers to word size.
Word size determines the size of the chunks of data a processor can look at at once. 64-bit processors can look at larger chunks at once.
The new Apple processor is most likely only 40-48-bits, BTW.
Intel is showing, not shipping, which would put Apple ahead until someone else ships one, not that it's all that significant anyway.

Doesn't anyone realize it yet? iOS and the A7 have gone 64-bit, not for the iPhone, but for the iPad and the iMacbook to be based on the ARM chip running OSX on ARM. The iPhone is just the beginning.
People were complaining years ago about Apple making an iOS-based laptop and how it could never replace a full-blown Macbook Pro, but the reality is that the processor will have the power and flash will be cheap enough for it to happen.
Maybe there will be a version of OSX for the ARM and a "laptop" to go with it? I can't tell you it will be more like an iPad or more like a laptop, but people need to open their minds regarding the future of computing. It's not Intel Desktop or Mobile x86-based CPUs. It's ARM.

I still don't understand which apps will run better on 64bit? Maybe games, a'though infinity blade III didn't seem particularly impressive versus the previous version. All this bragging and chest pounding, but. what is the tangible benefit?
You must be a very fast eater because on my Galaxy Note 2 closing the browser and starting camera app takes about 1.5 seconds (combined). Be careful with exaggerations for some people may believe you. Then of course it may keep some iPhone owners happy longer if they believe claims like yours and think that Android is slower than iOS.
----------
The answer is very simple - the only apps that are going to benefit will be the apps that do a lot of calculations with double point precision (like nuclear reaction simulation). In case of phones what applications would that be? I have no clue. As far as games are concerned, the bottleneck is usually in the GPU and 64-bit CPU architecture will not help here at all. Most likely at this point 64-bit switch will be detrimental for phones and even tablets. It will help is and when RAM reaches 4GB or if Apple wants to switch to ARM chips for Macs. Neither on of these developments is likely in the near future (2 years for former, never for latter)

What if you download using iTunes to sync to multiple devices?

Except that the GPU is integrated into the A7 SoC, so it might--but we don't know exactly what Apple has done with it yet, as far as I can tell.
Apple has no knowhow for GPU development. They use solutions from other vendors. Besides, GPU bit-ness has nothing to do with CPU architecture. It's a separate part of SOC. What matters is the bit-ness of the bus between CPU and GPU and this one also is a separate thing from CPU architecture.
