Repairability is definitely a factor, but don’t forget considering how long a company will support software updates for the device, how the device meets your needs no only today but 5-6-7 years from now, and your options for repurposing the device once it reaches EoL.

That won't solve the software side. My previous phone was still working, but then Google fucked up the software. The first because it required some new ssl standard for all connections that the phone didn't support. The other one because google added a whole lot of local Infos, pictures and features to the map that could not be disabled, therefore rendering my Navi to a unresponsive, slow and battery draining app I could no longer use. And then there where some apps that would not run because my os was to old.
