Right now, having devices which require both expertise and expensive machinery means that the cost of going to someone to repair it will increase over 10 folds, making a full replacement a financial and sound choice.
If my CPU doesn't last for 10 years but I can change it myself in minutes, I would rather that than throwing away everything else I still love and is still functional just for promised extended reliability (which is just a matter of statistics and profit margins at the end of the day).
