The closest thing to what you're describing seems to be the Librem 5[1]. It's a bit of an investment to get into now, but if you believe that such a product is worthwhile, I think it's worth backing even at this stage, just to show that the market is there.
Looks like a lot of people are mentioning this one, so buyer beware that it's in the kickstarter stages & it's not currently possible to buy outside of kickstarter
Yes but they actually ship hardware right now (laptops), just raised a round of funding, and post regular updates on tangible progress. A safer bet than most, I'd say.
