I have used paper but finally with my Remarkable 2 I can keep my paper workflow/feel and don’t waste paper .
But of course the Remarkable has an ecological footprint too, just like paper has.
A non-zero amount of energy and resources went into manufacturing the device. Extracting and shipping metals/oil/silicone, refining those materials, then constructing the display/CPU/motherboard/other components, then shipping all the components to the assembly site, then shipping the device to the store/warehouse, etc. It’s a lot more complicated than making paper.
Then multiple times per week the device has to be charged, using electricity that might come from a coal power plant in worst case.
I’m not saying one shouldn’t buy a Remarkable. But I don’t think it’s fair to say that the Remarkable is less wasteful than paper before doing a life cycle assessment.
