The way I see it, we will reach a point where the advancements will become fairly minor, like computers today, and there just won't be a reason to upgrade so frequently. carriers will probably have to work harder to convince people to sign up for new devices and such.
Smartphones and tablets will be looked at the same way people view computers and the industry will move on to something new, like wearables for example. 5 years ago the smartphone was a luxury to most, now it's more of a necessity. You can already see this happening with the decline in iPad sales. Once the balance between solid hardware and a mature OS is found, like on computers, there won't be anymore reason for people to keep updating so fast. There are only so many gimmicks that they may be able to throw in before people start to realise their old device is just fine.
In 2010 smartphones were a luxury? Hmm I don't know where you live, but long before 2010 most people I knew already had smartphones. I'm not talking about phones with touch screens - those very rare(r) indeed, but for example I had a Nokia E61i and many others were using such phones. But whatever.
I don't think there will be a decline in updates, simply because it brings money. If they wanted they could make the perfect phones, but they don't because everyone would buy it and then nobody would buy any other phone for the next 10 years anymore. That's quite common as far as I know. Didn't Good Year produce the perfect tire, that could hold forever? They got a patent on it, but simply don't sell it. Else the tire industry would collapse.
Also, phones are automatically linked to carrier plans etc. very often. Computers are not, so most people pay the computer instantly, whereas for iPhones people often get a plan. Even if they don't cost much less. But it subjectively appears much less for the consumer.
No one is saying Apple doesn't want to sell new phones. Of course they do. That said, if you think the only difference is visual appearance then this conversation should end here since you make it clear that the ignorance factor on your part is too high to have an intelligent conversation with. I don't know if it's intentional or not, but it is what it is.
I tried to search on Google and couldn't find anything. Will you finally tell me now what it is? Please? After asking 5 times. This is becoming ridiculous. I want to know which are the things that take up resources. Please show me the Google link where you found this also.
The way I see it, the OP is trolling us.
Please, do us a favor, and just go to bed.
You want fast..but have an iPhone 4...sounds like beggars can't be choosers. Not willing to spend 800 on a new phone? Keep the iPhone 4, and use it accordingly.
I don't have degenerated Hulk-hands, so newer iPhones and their XXXL size are not a solution for me. Neither are devices without iOS.
PS: My Mac cost probably more than your car.
But I love how you measure yourself with materialistic things. Buying a used iPhone 6+ on eBay as "broken item" to then be able to hate on other people's (older) iPhones. Haha! Women must jump on you.
