You couldn't be more wrong or old. those days are looooong gone. I'm in Sing and HK and i did the same as this author, i asked why people liked it, pure functionality. most common response "i no longer need 2 devices" that being a phone and a tablet. Btw, its a big hit in Europe, must be a face thing there too then. Sorry to say but you sound like the irrational fan boy i try to avoid on silly blog sites.
iPhone have the best form factor for a phone which is a smartphone but that doesn't mean people might not be willing to experiment. If you are carrying anything bigger than an iPhone than it either isn't in your pocket or you are wearing a suite with generous pockets, either way it's clunky. But, one may start having these intermediate screen sized gadgets as part of their mobility bag which would imply that potential iPad customers are getting diluted.
Easier said than done. When Jobs took over Apple, he streamlined Apple product line. It paves the success path of Apple. Managing one product is not easy. Managing 10 different products of the same kind is a pain. I am sure there are a few model from other vendors that don't sell enough to cover the cost of developing the product. Product streamlining is a double edge sword. So is product diversification.
Most people in the other parts of the world covering Asia and Europe don't drive often. Public transportation is the primary mean to get from point A to point B. Therefore, they usually carry a briefcase or a small backpack. If you carry a small backpack mostly standing in a bus or a train plus a mile of walking, you will likely prefer to carry less than 5lbs, definitely less than 10lbs. A small form factor will help reducing the weight. 1 less item will definitely be the choice. Instead of carrying 1 iPad and 1 iPhone, why not carrying 1 bigger screen smart device? If they have to, they still have room to carry 1 more ultra light weight laptop. Make sense?
With the S3 Sam stole a lead over "frenemy" Apple because they used their own 32 nm HKMG process to build the QUAD CORE Exynos in it. Can't drive a larger screen unless you have a faster Graphics processor that won't burn too much battery ( transistors with HKMG ). Samsung was holding back their 32 nm process from Apple when the A5 or A5X came out. Won't be too long now b4 we find out what Fab process the A6 (?) for iPhone5 is built with - 32 nm HKMG from Samsung or maybe they would shift Fab business to TSMC ( 28 nm LP ) to teach Sam a lesson ?
No, the concept you are describing has nothing to do with accuracy. You are merely expressing a desire to present different information. Either of those sets of information could be accurate or inaccurate.
"I wonder if Samsung should sue Apple for stealing the new smartphone look-and-feel when a big screen iPhone 5 comes out?"
Yes by all means. The patent office should start issuing patents on particular dimensions. I want to patent 5.5 inches. Anyone that builds anything of that length or width would pay me a royalty on my amazing invention.
