Leave it to the MR forums!!
Seriously though... with all the available tech (NFC, wireless charging) we're getting a
barometric pressure sensor?!? I would hope this is for the iWatch and not the iPhone.
I'll wait until Sept. 9th and hope to be wow'd, but right now I'm sitting here shaking my head. Give me something I give a crap about.
NFC is never, ever, going to be on an iPhone. NFC, first of all, sucks, but most importantly, Apple has already brought out a much better technology themselves, called iBeacon, piggybacking on Bluetooth 4.0 LE which is a far more widespread technology on devices and cheaper to implement in locations. I don't know of anyone who has ever used NFC for anything, but I've personally used iBeacons and know lots of other people who have as well. I hear about iBeacon rollouts all the time, and it's been less than a year since Apple officially brought out the technology. In a few years it'll be everywhere.
Why would Apple settle for an inferior technology that is never going to catch on, when they're pushing their own standard that's being rapidly adopted?
Thats a bit short sighted. I am not sure exactly how it would work, but if every iphone fed weather related data and location into a system I would imagine it could do big things for weather analysis/reporting/forecasting. NFC and wireless charging are small things that exist, that may or may not be useful, and that Apple could easily choose to implement with little effort - not having them is a design choice. But access to hyperlocal weather data from on hundreds of millions of GPS located portable weather stations seems much bigger and more exciting to me.
You're absolutely right, lack of NFC integration is a design choice, and the right one at that.
As for adding new sensors, I'm always for it even if I can't personally think of a good use for it myself (though, like you, I
can think of uses for a barometric sensor). Any time somebody says they think a new sensor is useless, I just have to laugh and shake my head. The same thing has been said about basically every sensor Apple has added to date, and yet, developers keep coming up with innovative new apps using that sensor data. More sensors mean more new apps using those sensors, making your phone more useful in ways you haven't dreamed of yet.
Eventually, our iPhones are going to be like tricorders. This is not a future we should be fighting.
