DeGoogle Yourself

I think we're watching a major shift happen, similar to when smartphones took over. At the moment, I can't see the market ever opening back up the way it was, because apparently smartphones are produced at a loss. If there's really no way to manufacture them at a reasonable cost, they're never ever gonna let go of the hardware control ever again. The last couple decades were just a long con to grab market share, now we're in the late stage where they lock down and grab as much data as possible, laws be damned.

I just spent too much time writing another comment on this post, but I have the same wants as you:

recent processor, a good camera, GPS, Tailscale, 18 hours of battery life a good enough browser to get to my bank and edit photos

I really think we're watching the smartphone era fade away for tech-minded people, and it's time for us to just ditch the expectations and let go of the all-in-one convenience. Phones for talk/text, dedicated devices for everything else. Most of these specs you mentioned can be exceeded in a compact touchscreen 2-in-1 netbook, for about the same cost as a flagship phone, and be fully compatible with Linux. Currently tablet sized, almost small enough to fit in a purse, but hopefully smaller variants come around in the future.

Only issue is GPS and camera. Phone GPS modules aren't very precise as it is, hopefully we get a compact USB receiver someday. And cameras never really made sense in a phone to me. Loved the convenience, and I will miss them dearly in my future phones, but a cheap digital camera will beat all but the high end flagship phones, both in price and image quality.
