The situation won’t improve until some big company goes full “IBM PC” thing with open AT, ISA, VESA, etc tier standards for phones.

This phone is better just because you can open the case. Spare parts are still provided by a single company. Not a big step ahead.

Better than nothing though…

With all respect, I still think an iPhone is a better chance at having spare parts many years ahead. I am confident I can find some spare parts of iPhone 4S. Would that hold for FairPhone or a similar phone? If not, the benefit is an illusion. Unless, I think, you can produce that part yourself.
