This is based on an assumption that making the device serviceable is actually going to help with this. I'm pretty sure that's just an assumption, mostly based on a hope that we can keep consuming like we do and somehow not wreck the planet if we just pick a phone with "fair" in its name.
> That's essentially whats happening with iphones, because Apple refuses to give customers the option to take their phones to reputable repair shops by prohibiting suppliers to sell to repair-shops, or in some cases using DRM to prevent repair.
Apple actually takes the old phones and is fairly good at recycling and/or refurbishing them. If you're going to toss your phone with that being the case, I somehow doubt you'd repair them either.
> Why do you assume that the phone has to be bulky? That's simply a lack of imagination on the part of designers..
I can imagine a phone that's also a horse and a vacuum cleaner, but it's not imagination that helps. Extra demands restrict options.
