A few weeks back I was wailing and gnashing my teeth, about all the perfectly functional hardware that will go to e-waste in Aotearoa because of the 3G turnoff. In response, someone (can't remember who, sorry!) was schooling me on all the reasons why it's impractical to re-purpose obsolete mobile devices, eg as home media servers.
Anyway #TIL there's a company in the EU that's found a creative solution to that problem;
@strypey what a great idea!
