"You can't have thin and lightweight without glue."
Disagree entirely. My wife's laptop is a Samsung Series 9. Very thin ultrabook on a par with a Macbook Air. Opening it up involves removing half a dozen small screws, inside the battery is held down with two more screws (not a drop of glue in sight), and the SSD is replaceable. Unfortunately the RAM is soldered down, so it isn't perfect, but it's a lot more easy to service than an Air - despite being no thicker.
Alternatively, pop open a Lenovo X1 Carbon and there's also no glue, plus the RAM is also replaceable.
You can build an ultralight without lots of glue, and without soldering everything in sight - if you want to. Face it, Apple doesn't want to. They want their products to be disposable so that users keep buying replacements every few years.
