[citation][nom]istank[/nom]While Apple does have the fastest processor in their devices it is not the most powerful by far. Its users are blinded by marketing and the closed system that Apple promotes. The OS does not allow the A5 to reach its potential. This processor would be an absolute monster on an OS that has true multitasking capabilities. The capabilities are there for the iPhone 4S and the iPad 2, but with the measures put in place to limit the amount off apps that can open and by pausing apps switched to the background it reduces the usefulness of such a great processor. All in the name for fabricating extended battery life.This Samsung modified ARM 9 is a great piece of hardware. Too bad the vendor that got the processor has no clue what they have.[/citation]
The iPhone 4S has the fastest CPU/GPU combination, yes.
However, the CPU element in the iPhone 4S is only 'as good' as the very best Android CPU's, it's the GPU which is so far ahead. What makes the A5 processor work so well despite its lower clock speed is the fact that iOS is designed around it, and the chip is designed around iOS. In other words, Apple manages a much tighter hardware/software collaboration which maximises both. It's more efficient method of handling multi-tasking also prevents any of the slow-down you may found with Android. I have an iPhone 4 - and I can honestly say I was completely unaware of any limit to the amount of apps that can be open. I type this from my Windows 7 desktop with about 40/50 windows open (literally) - I'm a big multi tasker, it's never come up on my phone.
Moving on to Android, we find the opposite scenario. Chips which may in theory be higher performance, tend to not be as tightly linked to the Android software which has to support so many different architectures. This fragmentation means that many Android phones don't realise the full potential of their hardware, and require more RAM to do the same things, and we see the slow-down as a result (and in some cases worse battery life).
With regard to 'closed' system, why do you think people are 'blinded' by that? What do Apple users miss out on due to the system being 'closed'? Remember, the source code to Android 3 was never released, and 4 hasn't been released yet. I struggle to agree that Android is even open, let alone the fact that it's a benefit. If you ask me, the fact that Android operating system is free is actually it's biggest drawback. Not only does it mean every big phone manufacturer other than Apple offers the same operating system (so struggle to differentiate themselves, meaning the profits are split more ways, between more companies), the release cycle also leaves many not-very-old Android phones out in the cold, not receiving the updates (for example the 17 month old Nexus One which wont receive ICS). On top of all of this, the 'open' app store on Android is also holding it back from business. It's well documented that the price of being open is a drop in security, and many experts have come out and said that iOS is far more secure due to the quality control process of the App Store. Pretty much every app that you could ever find on Android is available for iPhone anyway.
I just struggle to see openness as a benefit, to the end consumer, once they actually have the phone in front of them. Feel free to explain to me why it's a benefit, or what important tasks you can do on Android that you can't on iOS due to it being open. I'm open to persuasion.
Soon I will be buying a new phone, and I was half expecting the Nexus Prime or the Razr to be better than the iPhone 4S in hardware terms, to make choosing them easy, but I'm really struggling to find a compelling reason NOT to buy an iPhone 4S. I'll take my time though, see what Android phones come out over the next few months.
