I want to buy a computer (new/unused, ideally off-the-shelf) that
- contains absolutely no proprietary software by default, and
- can be used without installing proprietary software (it’s fine if non-essential things are not supported).
It should allow to connect to the Internet somehow. It does not have to be built-in, as long as there is a supported external device available that also only comes and runs with Free/Libre software only.
Sound output would be nice, too, but this could also be an external device (again, if a suitable Free/Libre one is available and supported).
I would welcome if it can run a (well known) GNU/Linux or BSD operating system, but I don’t want to require it.
Anyway, it should be a "real" OS, i.e., a system that allows users to update it and to install software; not a single-purpose system (like an e-book reader).
Browsing the Web, managing files, writing documents, listening to music, using the terminal.
No HD videos, no video/graphic editing, no games, no compilation … nothing that requires much power.
What I found so far
Problem: Not new/unused. They use refurbished laptops (i.e., they bought used laptops that came with proprietary software, replaced parts, flashed the firmware, etc.).
Earth-friendly EOMA68 Computing Devices offers single-board computers (and optionally corresponding desktop/laptop housings, whose design gets also published under a libre license). Its Libre Tea Computer Card will likely get FSF’s RYF certification.
Problem: It’s in crowdfunding currently. Could become a good solution, but only if they will be available for sale after the crowdunding period.
Just to be clear, I do not require FSF’s Respects Your Freedom certification. The difference between their and my requirements is that I’m fine with OS that make the installation of proprietary software easy, as long as the user has the choice.
