$800 phones that are essentially killed off a few years down the line yet people are fighting for the brand. I don't know why so many just roll over and accept this is the case.
Except the phone isn't "killed off." Your iPhone 4 hasn't stopped working, it just lacks the hardware for a new feature that wasn't available at the time it was released.
You bought that phone thinking it was pretty neat for what it did, and you even got some improvements for a few years. But there's a limit to how far older tech can be pushed, and it so happens that this new feature isn't in the cards for your older model device. That's all there is to it.
If that one feature is the ONLY reason you bought that rMBP, then I'd say you need to re-evaluate why you buy certain things, because that's a lot of money to pay for not having done your research.
TV's aren't disposible, microwaves aren't, fridges aren't,
TVs don't gain new features after the manufacturer is done selling it to you. Microwaves don't get OS updates and new features after the manufacturer is done selling it to you. Fridges don't gain OS updates or new features after the manufacturer is done selling it to you.
So when Frigidaire or Amana or GE comes out with some new appliance that does some whizz-bangy thing that your three year old appliance doesn't do, do you complain that they are
making you throw away your old TV, or fridge, or microwave?
On the other hand: Even on older OS versions, your current iPhone 4 can get new apps and do all of the things Apple said it would do when you bought it, and even a little bit more. And it will still do all those things for quite some time yet. You got your money's worth.
Computers aren't (apart from rMBP's with soldered parts)..yet we are happy to accept that a bit of kit that costs more than alot of other electronics is just a throw away item.
On the contrary: I don't throw away my computers simply because some shiny new thing has come out that my three+ year old kit can't support. I purchase knowing that technology evolves, and new things in the future might not work on what I bought now. So I consider whether what I'm purchasing serves my needs enough to be worth using until I'm ready to buy something new without feeling bad about it.
Oh no my phone is 3-4 years old, guess I should ship it off to a farm where it can die of old age in a happy environment.
Or you can just keep using it, because, you know, it still works. It just doesn't do this one thing you didn't even know it couldn't do, because you know... that thing didn't even
exist until right now.
