that is called planned obsolecence and all manafacture love it so much . that where their profit came from . obsoleting their old device much faster than it needs to be

Totally agreed.  All one needs to do is think of all of those small mobile phone shops that are making business out of repairing phones and replacing screens.  Quite a large segment of the business would go under if they changed phones to be longer lasting.  I still can't get over how very expensive those phones are.  Where do people get all of that money from to not only buy one phone, but to be eager and do almost anything to upgrade it to a next and then a next phone. For me it is very wasteful.  Not to mention littering the environment with obsolete models.
