Its Apple's problem if they dont have infrastructure to repair Iphone, why are they penalizing customers.
It is just a fact of life that modern electronics designs do not lend themselves to inexpensive repairs. Glues require no extra fastener parts that add weight, bulk, & cost; & usually result in stronger products. (Aircraft are now more glued together than ever before for the same reason.) Ever larger & more integrated sub-assemblies allow much more functionality in less space, with fewer failure points & lower manufacturing costs. There are similar advantages in designing connections that are not robust enough to withstand repeated handling, flexing, or repair, especially with printed circuits & ribbon connectors.
Apple could design iPhones to be much less expensive & easier to repair, but they would be larger, heavier, most likely less reliable, & cost more upfront, which would penalize customers more on the average. Obviously, it is frustrating if you need a repair, but their really is no other practical way Apple could build something like the iPhone.
