Galaxy SIII is
thinner 1mm thicker (8.6mm versus 7.6mm) with an equal battery life
but a bigger battery because it hogs power, LTE
implemented with two power-hungry chips instead of one, more RAM
because the inefficient software needs it and
50% faster
-clocked, power-hungry processor
with slightly worse performance.
Fixed that for you.
The S3 and all those giant Android phones remind me of muscle cars. Big cars with a giant engine under the hood and a bigger gas tank because they burn through fuel like nobody's business. They ultimately achieve the power and they've got plenty of cup holders, but you end up with bad fuel efficiency and cruddy handling.
The iPhone reminds me of a Porsche with the fuel economy and price of a Honda. It has a consistent and beautiful design language, it has the most efficient and best-performing technology, it handles like a dream and gets great gas mileage. You pay a fraction more but you get something that not only holds its value but has the highest ratings on customer satisfaction for many years in a row.
Any idiot can make a bigger box for a smartphone and shove more stuff in there, just like any idiot can double the weight of a car by throwing in a bigger engine. The innovation comes when you find ways to make what does exist run better. Apple's A6 is running at 2/3 the clock rate of the processor in the GS3 and yet it is edging it in bench marks. That means more instructions per cycle and it means better use of power.
NFC is the biggest joke of a feature in any smartphone. It requires a giant antenna that gets wrapped around the battery in most phones, it exposes your phone to increased security vulnerability, it drains battery, all in the name of being able to use it a few times per year to make a mobile payment. When I can do away with carrying my wallet then NFC mobile payments will matter. If I have to carry my wallet anyway because most stores don't take NFC payments then why make sacrifices in my mobile phone to get that feature.
I want features that matter and I want the features that I have to work better. That is what Apple does and that is why 2M folks pre-ordered the iPhone 5 in the first 24 hours of availability. That is why 63% of Australians surveyed who own a Samsung smartphone said they are switching to the iPhone 5 and Samsung's own followers on Twitter and fans on Facebook are saying that they'd rather have an iPhone (
