Even 4.7 inches is almost too big. Steve Jobs had the right idea about being able to use the phone with one hand, and there is also the consideration that for men -- at least for many of us -- the phone needs to fit comfortably in your front pants pocket. I'm certainly not the only guy who will refuse to buy a phone that I can't carry unless I use a belt clip.
One size fits all is dead people. Look around you. Apple needs to change to continue to stay in the race and 'Steve's Way' is strategically outdated. Even he urged his people not to ask themselves what would Steve do. With larger screens on phones inevitable, tablets look to be the next market smartphones will canabalise. Lines between them will become increasingly blurred. Better late than never Apple!
I have an iPhone 4 and really like the features but HATE the battery life and struggle to see the screen given not so optimal eyesight. Perhaps there is a great future for a larger screen phone but even with the smaller size I don't find it convenient to put into a pocket and don't want a belt holster. It is about the right size for the job but too big for carrying around, I have a love/hate relationship with the phone. Love the features and capacity hate the short battery life and size. Not sure what the solution is, but would love to hear from others if they have a good solution.
Solution is choice.. Big or small, things break.. Smartphone market which is well and truly established by Apple is fragmenting to what used to be the 2G/early 3G market..when Nokia used to come out with 8 different models a season.. That's life.. Question is as a business, will Apple's management allow screen sizes to dictate loss of share.. In any event, in some shape or form, headsets will come back and putting any sized gadget next to your face seems somewhat archaic.. the days when even larger tablets don't provide a simple voice/call function (which is what basically divides the iPhone with iPad) looks to be coming to an end.. especially as voice will eventually cost subscribers nothing forcing carriers to begin more aggressively subsidising of more data consuming phablets of any form in the future.. its inevitable in my opinion..
