To each their own
There is nothing wrong in producing light and thin computers!
For less volume and weight in my bag, I can have an MacBook Air *and* an iPad (with a case) than an "normal" notebook. Yes, it costs more. But if it is possible to do technically and is still affordable why not do it? With this combo you get well over 17 hours of computing in two different form factors.
These devices are of course repairable. Might be not with the typical low-tech tools "normal" users have, but after all, those are high-tech computing devices. It has also nothing to do with being environment friendly. The MacBook Air and the iPad are made out of Aluminium, which is an well-recycling material -- unlike the typical laptop that has all kinds of weird materials.
I believe this is all non-issue - just to fill the idle time arguing.
