I’ve really enjoyed using PINE64 products. I use the excellent Pinecil soldering iron which is fully open source. I used a PineTime smartwatch until I got it water damaged (rip) which was a ton of fun to use. I have a pair of PineBuds wireless earbuds (default firmware is not open because of proprietary ANC, but last time I checked this is being worked on). I can’t speak for their laptops or phones, but I can definitely recommend the devices I do use if you’re willing to get involved in the community to work through and fix some of the existing issues.
