The 5S camera is killer. f/2.2, apparently a great sensor for the size and 120fps video is more than most pocket cameras offer. Manufacturers of point-of-shoot cameras can pack up and leave if this is a trend.

If lower end smartphones adopt this kind of camera (which I think is unlikely) then point-and-shoot cameras could have a problem.

However, comparing a $600 iPhone to a $70 point-and-shoot is not really relevant.

Earlier quoted context omitted.

What a laughable excuse. It's been this way for years.

Apple will adjust pricing based on currency. If the Australian currency is getting weaker it may be because the emerging markets that it depends on are seeing turmoil in their currencies because of the prospect of Fed QE tapering. http://www.telegraph.co.uk/technology/apple/4934147/Apple-up...

Apple has overcharged both in Australia and Europe for decades, even when the currency has been strong. It's simply because they believe that people who live there will stomach a larger price. It's probably true. It's still infuriating.

It results in funny cases where a Nexus 4 can be 1/3 the price of an iPhone 5.

If the expensive device is something people will buy and be carrying with them anyway for other purposes (phone calls, SMS, apps, etc.), then they have no motivation to additionally buy the cheap photo/video-only device and carry that with them.

It's the same reason why, if there was a $20 Facebook device, a $20 Twitter device, a $20 SMS device, etc., they wouldn't sell very well since the phones people already carry can do those things without needing to purchase and tote around multiple other devices.

Err no:

16MP, 12x optical zoom, upto ISO3200, Lens shift VR

The only good thing is f/2.2 which the Lumia 1020 has and is a better camera, 32Gb of built in storage (and SD card slot) for £200 GBP LESS than the 5s.

Apple are rip off merchants. Sorry.

> Next, it has an intriguing “motion coprocessor”, which I think pretty much means you can use your 5S as a fitness tracker with almost no effect on your battery life. My guess is that it's much more than this. It's for augmenting the GPS location with dead-reckoning, for places where the GPS location doesn't reach well, such as buildings or on subways, etc. Accelerometers are already pretty sensitive - enough to pro…

I doubt it's for GPS assistance. Motion sensors can be used to suppress Wi-Fi scanning and/or GPS localization during the roughly 89% of the time humans are not moving. Remember, phones continually scan for new Wi-Fi APs in the background even when the screen is off. On modern phones with a/b/g/n chipsets (32 channels to scan) and energy-expensive CPUs (i.e. Exynos) this takes a huge amount of power.

Motion sensors themselves are really energy-cheap but the main CPU needs to be on to sample them, which basically means that if you want continuous mobility detection you're going to burn through your battery pretty quickly, which is why it isn't used much. You can do some CPU duty-cycling, but wake-up and suspend overhead is pretty bad and can amount to as much as 50% of the total energy spent. I haven't done any measurements on an iPhone, but a GS2 Exynos 4 is a terrible energy drain, while an something like an OMAP 4460 (e.g. Galaxy Nexus) is much more efficient.

By offloading mobility detection to a separate chip you can bring down the overhead to tens of mW. The fact that you can use it as a step counter for jogging is just icing on the cake :)

Inertial navigation? It's an interesting idea, but I think if they were doing that, they'd have touted it in the presentation as an example of something they can do that nobody else is even thinking about. It's not like apple to miss an opportunity to try an distance themselves from the pack on their technical capabilities.

One thing I noticed is that they said the 5S is a "forward-thinking" device, implying that they've got more planned for it.

just a note (for you and for everyone else): stop whining about downvotes.

sometimes you are downvoted. it happens.

but more often than not someone upvotes you again, and then it just look whiny, espescially if you are second comment on the page (as you are now).
