True, they would have to do all that. They certainly have the resources.
It might not be as tiny as people think.
The articles claiming Samsung doesn't sell a lot of high end phones, always seem to leave out the Note, which is, if anything, even higher end than the regular Galaxy S model. They also leave out the other high end models still being sold.
Take 4Q 2012 as an example. Of the estimated 65 million smartphones Samsung sold, about 29 million were new and old high end phones.
Of those, eight million were Note 2, one million Note 1. Considering that Apple sold 48 million smartphones that quarter, nine million phablets seems like a pretty good number.
(The above also indicates that the idea that Samsung mostly sells low end phone is no longer true, if it ever was. A good guess is that they sell about 1/3 high, 1/3 mid and 1/3 low end.)
Yes, they have the resources. They also have the resources to make 20 kinds of iPhones. Or do anything they want, really. But just because they have the resources it doesn't mean its a good idea, nor a good long term plan. Also, Apple didnt accumulate these resources by having a crap ton of models. Sj always said he was even more proud of what Apple DIDN'T release.
Also, not sure what that graph is supposed to prove, cause I don't see the argument there for Apple making a larger phone. Note shipments went DOWN, not up. Also, like I said, how many of those would translate into iPhones instead? Even if Apple does make a larger iPhone, I doubt it will be as large as the note, and Samsung+ others will ALWAYS have larger phones. There's no indication that Apple will suddenly grab the huge phone market. Samsung is coming out with 5.8-6.3" phones. Do you think Apple will release anything close to that size? No. Again, there has to be enough evidence that the increased potential sales from 2 models will offset all the other disadvantages, and I don't really see it. Especially if Apple continues with their trend of keeping older models at lower price points. How many models can they possibly sell at once, while giving each model sufficient attention? I can't see more than the current 3. And if they DO decide to then drop older models at a quicker pace, that will further dilute the value of te iPhone and create less consumer confidence. Having the phone continue to be sold officially for 3 years guarantees that your phone will be supported for that long.
