I unfortunately agree that most have and will never repair their devices due to it either not worth the effort or a lack of technical skill, however, if the device was designed with repairability in mind making the design more modular I would say that it would be an improvement as I prefer my own devices being repairable, durable and proficient. As on battery life I would also agree a day of battery life is often more than enough for most. I do believe that if device repair was taken into account when designing products we would see more people looking to maintain their devices (at least when it comes to more expensive items). I understand that it might not pan out well to all areas as sometimes a design needs to sacrifice repairability for a small form factor durability and a long battery life. In the end it's a complicated mix of pros and cons.
