"If nothing else, the presence of six Apple items here, we would hope, should serve as a wake up call to Apple CEO, Tim Cook: Make your products more repairable, and thus less likely to wind up in landfills."
Or maybe this is their plan the whole time, make something impossible to repair forcing your customers to buy a new one. Also theres the fact that getting any apple product repaired by apple is going to cost 50-75% of the original purchase making it hard to not buy a new device. On the glue note it can be done for one of a couple reasons; it will make the phone slightly heavier and a lot more solid, good for feel in hand but when you drop it the energy of impact has no place to go but right into the glass, possibly resulting in more broken screens. The other reason I can see is manufacturing, they just glob it on and seal it up and thats a good days work, ones that don't pass QC end up as unbranded phones for sale in china. Either way you look at it, the end product is just going to end up in a landfill, weather in 1 year or 2 years, the planet will suffer about the same in the long run.
