I'm sure Apple engineers are smart enough to make this work without MacHeads getting all worked up about resolution, scaling of apps etc.
In fact 4.3" is the Standard Size, even Samsung is enlarging their Galaxy S II from last years 4.0" to the current standard of 4.3". Therefore it would be appropriate for Apple to also migrate to 4.3".
Unfortunately I doubt Steve Jobs ego will allow it since it wasn't an Apple first trend.
As much as I really like my Apple devices, they could be even better if the sole focus of Jobs was to build the best products ever.
Instead he makes the claim Apple does, backing it up with near fraudulent claims & hype.
If Apple would relax, let go of their fear & paranoia of Google, Adobe, & anyone else that Jobs hates, Apples products _would_ be really awesome and even more profitable.
Look how much they are selling! Look at the massive profits! Just think of the potential if 100% of their focus was on doing their best, instead of sticking their nose in others business.
If Apple would drop the attitude, their products would really be world class.
You're new around here.
I've been here for a bit longer, and I can't tell how many times that I have read virtually the same prognostication you embrace right on these forums.
That would be a decade that I have been following Apple on the forums, and some 27 years since my first mac, a 128 in 1984. Since Steve Jobs return, Apple has been on a tear, literally redefining entire product classes, and that is pretty easy to verify what with the internet and all.
Bet you aren't aware that Android wasn't a creation of Google, but a purchase of technology, and that that technology was pretty much like every other "smart" phone at the time.
Apple shows up with the iPhone, which redefines the smartphone, and now it is the standard by which all other phones are compared. Back to the drawing board went Google with Android.
I would agree that one of the advantages of the Android (I'm not sure that I would call it a platform yet) is that each and every manufacturer can add features at any time, creating hundreds of variants, whereas Apple just added its second model (the Verizon phone) split into minor variants based on memory, into the current generation. From an engineering standpoint, Apple is constrained by its decision to market only a limited product line to a supply line that must provide 10's of millions of exactly the same part (an example being the display for the iPod Touch and iPhone, or the AX chip which also finds its way into Apple TV) and has yet to meet all of the demand. For that effort, Apple gets to negotiate that best pricing and availability, and is able provide funds for capacity creation. This is how Apple maximizes profit.
Apple is quite aware of the Android challenge, but I highly doubt that Apple has the inclination to vary its profits model to enter the race to the bottom that will surely occur with the Android business model (please note that Google has made only half hearted attempts at manufacturing, preferring to maintain its dominance in advertising revenue). So if Apple does response to market challenges from Android, it surely will be deliberate and carefully implemented, with the benefit of synergy with the entire Apple product line.
In conclusion, I haven't a clue if or when Apple will build variants of the current iPhone with a bigger 4.3 inch screen, but should it do so, it will be for the entire product line for many generations.
