I've been looking into switching away from apple and try to buy more EU based services and products.

I love the concept and might just buy one to support the project, but I want something sleeker for my daily use. So I'm considering slimbook & tuxedo atm as buy-from-eu options.

They’re also working on MNT Reform Next, which is the sleeker version. It should be coming soon-ish, so if you otherwise like (and can afford) the classic Reform, you might want to keep an eye on it.

Where do you want it to be produced? Assembly is not production, essential parts production is.

Then you are left with no options at all. Raspberry pi, maybe.
