That's fair. I'm assuming the majority case is simply: device breaks, can't be fixed easily, gets thrown away. I think we'd need some actual data to have a meaningful discussion about it.
That's a reasonable assumption. Anecdotally, on my local high street, there are at least 5 places--one official Apple service centre (not an Apple Store)--that offer battery and screen replacement for all mobile devices and tablets. At least 3 have been there for more than 5 years, including the official Apple one. There must be some demand for them all to survive.
